i belive the most standard strat radius neck is 9.5 where as ibanez is 16. So there is a pertty large difference.
The wizard is flat and wide, really the only way to know if you like i is to play it, i can see where that would be a problem in your case.
as for the 9s or 10s, that would be really more of a preference on your part, 9s would make the tremelo a little less stiff, but either way it would just be what you'd like, i have 10s on my usrg30 and 10-52 on my rg570 and the edge on my rg570 is easier to use then my lo pro on the rg30.
