Questions for the Drag Racing Gurus

Granted that my car isn't really set up for it, yet, and I haven't really ever drag raced before, but where I am moving to, there won't be any road racing tracks close by. There are plenty of 1/4 mile and 1/8 miles strips, though.

What are the popular opinions on, or experiences with, Line-locks/Roll Controls, Launch Controllers, and what nots?

For instance, has anyone used N2MB's WOT Box No-Lift-To-Shift with 2 Stage Launch Control? Does it really deliver the promised .7 sec quicker ET? Seems a bit much.

I was considering either the SLP Line-lock or Hurst Roll Control and the MSD Launch Master just to get me started. Oh, and some smaller rims with better meats.

That's your topic, now discuss it amongst yourselves while I sit back and learn, please.
