Hub Stacks?

[Blemski]

I am new to the forum on this site and i was wondering what you guys think of the hub stack’s on the yyf’s. Do you recomend them and is it possible to put them on other yoyo’s? Also i just ordered a grind machine, what is the general opinion on it?

thanks

They’re fine. They’re fun to play around with some, but nothing really all that special. You can put them on other yoyos that have hubstack posts, but usually those have hubstacks already on them. The Grind Machine is a good yoyo.
