Do you think there is any way I can compete by just using T/B.
Thanks again Chris for your great advice!

Regardless of the delay, you are just leaving off the trans brake, just a tiny bit later
So, sure you can compete that way.
Typically (although this is not always true) a "pro tree" -- all three yellows flash together -- is a .400 tree (actually .370, but let's not go there right now), and a "full tree" -- the three yellows flash in sequence -- has each light .500 apart. However, there are some classes and places where this is not the case (and with "cross talk" it's not always exactly .500, again, that's another discussion). In competition, it's decided by the class. Super Comp is a .400 pro tree, Top Dragster is a .500 full tree, for example. Bracket racing (name your dial) is all done on a full tree.
At a test and tune session, they usually say "lanes one and two for pro tree, three and four for full tree" and so on. And you can always ask the guy in the staging lanes. Most places on a T&T will even give you what you want. Just hold up 4 fingers for a pro tree, 5 for a full tree, they'll get it going for you.
As for IHRA, couldn't tell you. We're 1000 miles from the nearest IHRA track...
