In recent past, I've used L7, no kicker, with very good results. I still have yet to try AKA, though would like to sometime soon.
Now I gotta give a shout out to some guys in TX. While at RCPro Finals, I bought a bottle from Indy RC. I really, really like this stuff. It's very thin and it works through the bead quickly. If it gets on the tire, in open air, you can actually watch as it evaporates. It's wierd...but in a good way. Definitely worth looking into.
