well even if your putting in the line lock, if i was you learn how to burnout and launch without it...thats the best way in my opinion...then once you have that stuff down pretty good, arent too nervous, and have made a few passes to get your feel for everything, move on to using the line lock...it really shouldnt be that big of a deal once you get comfortable and have enough seat time at the track...dont sweat it man, everyone was there once...do what is comfortable for you, but im pretty sure that youd be more than capable of hitting off the button when you launch
