I have been reading alot! Hiwin hgr20 seems to be everyones choice. Ive read that 15 is to small.. Is this purely in hight or is it width aswell? How about the egr series?
Or even better for the wallet, chinese hiwin copies.. How do those match upp?

Been looking at iko and thk aswell but they seem to have alot of series with only two ballraces and i guess that this inte ideal?
