Cool, Trips your experience with them sounds good. Coarse-R, your experience with them also helps. I've been running Sorex all this past summer and have had good results with them. The only experience I've had with the cs take-off's is that in the last regional ROAR race I attended(onroad region 6), the 1st and 2nd place winners of the A-main in both stock and mod used them. They were using the 22's with the blue echo inserts on an outside permenant track with VHT sprayed on heavy. The outside temp was around 75-80 degrees. Hope this helps.
PS- SirSpeedy, Speedo or Trips, If its possible, could one of you change the thread name to Tire and Insert Thread on the Electric On-Road page. To me, inserts are just as important as tires are when select tires/inserts for a certain track. Thanks for an awesome r/c forum-Proudwinner.
