I have discovered something and would like to share it with all of you. Somebody said that you could see the difference between a pt57a and a retail prestige mp, because the ridges on the throught of a pt57a where sharper. Since we all seem to know because the pt57a and pro tour 630 come of the same mold. So i started searching for some pictures, and indeed the throught on pt630 seemed sharper then on the retail youtek. So that would mean that the mold of the pt630/pt57a and the youtek prestige mp are different. But the i started looking for pt57a in microgel/youtek prestige paint. And to my surprise it seem to use the same mold as the retail microgel/youtek prestige. While the flexpoint pt57a and earlier prestiges used the mold of the pt630. So can we say that the pt57a is just the type of layup and isn't just a particular mold? And if so, can we say that the tgk238.x is just a type of layup and not a particular mold? And if so, can we say that tgk are just lighter retail stick with the same layup?
