Everybody has their own opinion. I don't see a lot of "comp cars" at competitions. Not to say that they're not there. I just don't hear of anybody anywhere in America that is really into the sport ever using them. But, I don't know everybody so that could be why.
Again, I like Yok. I'll endorse yok. To me, it's the best. To someone else, it may not be. But beside me just thinking it's the best, there's a lot of people that have been doing this way longer than me and who are way better than me that agree with me. But, to each his/her own.
