think the kyle strait's are better.
My advice after wearing both the six six one kyle strait and the six six one evo knee pad......... the kyle strait is more substantial. The padding over the knee cap is more substantial and I believe it would be better for a high speed knee impact or sliding. On the other hand the evo is more light weight and less restrictive. However, I am not sold on the evo d30 technology, as from the first day of messing around with it, I have not been able to get it to stiffen up and protect like it claims. After wearing the Kyle Straits for some time, I think I will return to those.
