CRT Valve Body

Okay Guys,
I ordered a Turbo Action reverse pattern valve body from Summit Racing. I was actually looking for a valve body that applied the low band but (as usual) Summit didn't have one. I ordered the Cheetah valve body (P.N. TAC-17156) as I've always liked the firm shifts and a lot of people were pretty happy with them. I currently have a Fairbanks manual reversed pattern valve body in my current TCI Street Fighter transmission that I installed around 2000. It came with a automatic valve body but I wanted a reversed pattern manual. I had the Fairbanks valve body from a previous transmission and although (I thought) that it was in the transmission it never gave me the firm shift I was looking for. Well as you might expect it shifted the same in this transmission. My buddy Larry (64mopar) put a shift kit in his trucks and the shifts feel like you've been hit it the back of the head with a 2X4! Well when I went to Summit to buy the valve body I got the same line that I got when I tried to order the Mopar Performance air cleaned I wanted ("wow, we must have had a real run on these, we have 4 coming in later this week. If you put your order in today you'll have it by Monday") That was almost 2 months ago! I know that they are going to use the Covid19 excuse but they NEVER stock anything for Mopars even though they try to make you think they have it sitting on their shelf in their enormous warehouse well all know they are having it dropped shipped to your house from the manufacturer. Well I am thoroughly pissed at them so I started researching other possibilities. I see the John Cope (CRT) makes one WITH low band apply, Made in USA (by him) and costs about the same as the Cheetah. He does say I'll need a low reverse billet servo kit which will cost another $90.00. Are any of you using this valve body and are you happy with it. Thanks for your help.
