Converter. Trans brake questions.

Ok I'm ready to order my new ultimate converter (lenny recommends 3,500 stall).

I'm also gonna order a bunch of parts from CRT.

Should I just spend the long dollar and order their bilet trans brake?

I know converter stall depends on a lot of factors but let's just say perfect world for this post.

If I'm on the TB can I stall up to almost 3,500 and how does that differ from foot breaking?

While foot breaking with the new converter will I be sitting at the line at idle, then stab it and jump to 3,500 or can i foot brake to 3,400?

Also how does that affect my hole shot vs being at idle then stabbing the throttle.
One way I'm well into making power and having a solid signal through my carbs, the other way I get pump shot.

Remember I'm new to al this so please explain what you like, think is better any why?

Thank you for your time and advice.
