I have only ever raced 400 pro tree stuff index racing, usually 10 flat.
To me, big advantage if you are the faster car on a staggered pro tree because your more aware of when your side of the tree will pop based on his dialin and the difference.

I love it !!! after many years of regular tree racing I find I prefer it ! we run on a .500 pro tree in the 11.50 index and Pro Dial classes.. I deep stage !... 5 round Pro Dial Win last year in picture

If you regularly race a full tree it could throw off your lights. It did mine. I liked racing it for the day and did good deep staging. but they don't have it regularly for 12 second cars here so I won't do it again.

I have run NMCA open comp which was a pro tree dial, but I really have only ever run pro tree. I get bored watching a sportsman tree and my attention wanders.

Find out if it's a .400 or .500 pro tree.
I've tried the .400 tree. The car was quick enough. I wasn't. You'll probably need a mid 10s car for a .400 tree.
Never mind. Just realized who asked the question. 10 second quarters does not apply.
(Looks like all the classes are .400. You might enjoy it. I'd save my money. My reaction times aren't good enough on a .400 tree)

Yes, light car and quick releasing brake helps.
I am sure what the OP is looking to do will be on a 4tenths tree.
Most anything 7.0 in the 1/8 or the 11.50 stuff is 5 tenths.
6.50 and 10.0 or faster is all 400 around here

I have a light car now. I had a very light car then, with a decent brake, but not a lightning-fast one. I think the car might have worked well with a younger driver with a better internal r.t.
To a point.... I think the faster the car, the better chance against a .400 tree. Got to be able to redlight, and then it's delay box time.

Speaking of brakes ... I foot brake and deep stage on a pro tree , when I look at my fellow competitors in 11.50 index my 60 foot times and reaction times are equal sometimes better than my competition as my car leaves hard , my car is slowed down via a throttle stop from 10.80s to 11.50 my 60 ft times are 1.57-1.60 ( 1.47- 1.50 shallow ) mph are high 114s . When I run pro dial I will set the car up a little quicker 11.40s since my track runs mostly 1/8 mile thats 7.18 - 7.21. I have been considering a trans brake , my trans builder says he will modify my backup 904 for a brake . Since I only leave at 2,000 I don't think it will be hard on parts but I don't know if its worth it after speaking with other racers in the same class most said their 60 ft times and reaction times didn't change a whole lot. Same with an air shifter I have heard good and bad.

I can only relate my experience.
I believe my car was SLIGHTLY faster using the brake, compared to foot braking. . M y personal benefit of the brake was more consistent lights. Stepping off a button was easier than swapping feet. I didn't use a two step, just wooded the throttle at the first yellow, stepped off at the third. 5300 rpm leave.
But that transbrake leave was FUN! Small wheelstand with the brake, left flat footbraked.
My memory may be faulty, but I'm pretty sure deep stage was not allowed in super pro, our only pro tree class. Exactly why I ran pro. Full tree, no box!

Luckily deep staging is allowed in pro dial and 11.50 index , as well as my local tracks Pro and Sportsman classes . When I started pro tree racing I was going back and forth between shallow and deep , two very good local successful racers told me to go deep and stay that way ! I have and have done pretty well. I am at the point now were I don't like the full tree anymore. Several racers use a two step , personally I don't like the idea of misfiring cylinders to limit rpm. Same thing with plate systems to slow the car : I have tried the E Z plate system ( change plates with different size holes to restrict flow ) and the Willys adjustable plate ( turn the plate in or out to restrict flow ) and found that in my application they both killed to much mph. I use a modified Moroso stop which is a bolt to restrict throttle opening : in for faster out for slower... my usual 11.50 setup has my secondaries barely opening.

Sportsman and pro, deep was allowed. Just not in the pro tree class. Backwards of what it should be, in my opinion.

I have never seen deep staging allowed on a pro tree, that seems weird
My business sponsored an 11.50 index class at the Norwalk Mopar race for a few years.
500 pro tree, footbrake only, no deep staging, and courtesy staging in effect, so you don’t get these guys driving in and turning on both bulbs and watching the other guy get in, to be more ready.

Must be a Northeast thing ..when we go deep we always go in quick so we don't mess with the other guy., thats our courtesy. I roll in at rpm ( 2,000 ) all in one motion , I don't stop at the pre stage but bump into it and the final stage bulb. Your class looked tempting to me awhile back but the no deep staging kept me from attending. A few of the tracks I run at you are allowed to put deep on the window so your opponent and the starter know. At another track I was told to take it off the window . fine by me ! a few guys I beat told me I didn't know you were going deep ! If I am running a friend I will tell them . It did bite me in the butt last year though , I went in deep it must have thrown the other guy off as he took forever to stage and I lost my concentration and lost. Very few of the class champions across all the classes shallow stage . I use the rules to my advantage .. I am foot braking against I would say over half the cars in the class that have two steps and trans brakes in both pro dial and 11.50 index .

In my class everybody was footbraking, no brakes allowed.
Allowing someone to go deep would be an advantage. Your closer so your reaction will obviously be faster.
It’s to me more fun when everybody plays by the same rules.
That said, I footbrake in pro class at my track, most guys ( 95% use a brake) and some guys even deep stage.
Different animal on a full tree though.

You seem to have been racing for a while but I have NOT so, take this for what it's worth. One thing I can share with you about a .400 pro tree racing is the car needs to be tuned to get on the brake quickly. May take some carb tuning to get it right between squirters and pumps.
I have to run 0.015 in the delay box. I can red light on a .400 pro tree. I was mainly just wanting to know if people enjoy braket racing on a pro tree. We run the 6.00 class on a .400 pro tree.

I have enough of a built in delay being 71 years old , boxes not allowed in pro dial or 11.50 index around here !
Didn't like it at first. But after I got past th mental part it was ok
