In that case Id definately stick with sorex, I forgot to mention that we switch straight to sorex 36 from takeoff 27's when it really heats up...

the 36 is a great tire, very wide temperature band, and even works in colder conditions provided you can use tire warmers for the start.

go with Sorex if they are in supply, they are used in the states, thailand and most other hot/humid climates...
