Granted someone like the original poster has no biz using synthol, but it was my understanding that most pros do use it to some degree. Valentino, while interesting IMO, isn't a good example, he looks ridiculous. However, it may be useful to some very advanced competitors to stretch muscle bellies. I'd be interested to hear whether my notion of limited use among most pros is accurate. Its obvious in several, but these aren't the ones I'm interested in. Its the ones who use it for minor improvement which you can't id as synt-related.
