instant sticky?? good luck. as for that kit it is a good kit and not too tough to install, I am glad you got away from the rapid reload, I dont think that works in halo anyway. and it invoves dealing with the face buttons which can get very tricky!!!
I see you are fairly new to the site, how about soldering? this mod still involves soldering to the leds. just a small piece of advice, if you can afford to buy a premodded controller from the store, I would definatly consider it!!! either way good luck, some one will be here to answer any questions about the install if needed.mike stands behind his product 100% and there are alot of other guys around here that can help aswell.
good luck and happy modding
