imho, it's all a matter of taste.. try out the "big names" and see what feels right to you. For me, I love the Zhan Chi (Dayan 5) but some swear by the F-I or F-II. My Guhong (Dayan 2) was awesome for me until I got my Zhan Chi (Dayan 2 (GuHong) and F-II are about equal for me - they have different pros/cons)
But it's really up to how the cube "makes you feel" i think. try a bunch out and see what you think!
i hope im in the right place for this. need some info.
im trying to get info on good quality speed timers like the ones at comps. perferably one that i can plug into my computer, and or a nice mat to go with it. thanks
