10's sound good. I play drums for sound, not the "looks"
I know many people here do, but I record a ton and I go for what fits the music. If my kit looked really really odd or dumb, I'd try and make up for it with fantastic playing. I have seen all kinds of crazy setups. I never think about it twice if the drummer utilizes it. You could put a 6 inch on the rack and a 20 inch tom as a floor and if you make it sound good I'd accept it. Similar to if you have 7 toms and use 2 I'll probibly think your an amature. I watched a guy play a whole gig with a HUGE gong behind him to not hit it. That drove me more nuts than anything.
Use the drums you have, make them sound as good as you can. Don't worry about looks. Also that 10 is not that much different than a 12 at the end of the day. an 8 would be pushing that limit.
