"hands that can play a keyboard octave"... I think most people could manage that, really. I can just about do the 4th above the octave and my hands aren't particularly big. The keyboard player in my band can comfortably hit the 5th above the octave while playing but in fairness, he does have massive hands.
Errr... yes, anyway. Nice review, seems like a good product to me. I just got the CM Storm Spawn; my first ever gaming mouse and I'm immediately loving the 3600 dpi. Dunno if I'd be comfortable with anything more than that, though. Maybe.
