I think youll be fine with 600s for now. Especially if all you are doing is learning to fly basic manuvers like circuits, figure eights, etc. Granted that any FBL system works its best with FBL blades (cause thier balanced differently) with what your doing its OK to use 600s. once you start getting into more aggresive moves 620s and 640s will be the best, FBless types of course. Ive used everything from 600mm to 660mm and the best "Performance" I could get was 640s on a 14T pinion.
I'm assuming you are using somthing other than the LT head with your GY750....
showing a preference will only get you into trouble, 90% of everything is crap...
