10" or 11" brakes?

I'm putting together the 8-3/4 for my 69 Dart. Currently it's a 340/727 car, but I do have a 383/A833 I may go to. I have a complete setup, paid for, of 10" BBP rear drums on hand. I have everything to go 11" drums except the shoes and drums, which are easy enough to find. For fun, maybe even a little spirited street driving and corner carving, is there any huge difference between the two brake sets? Cost isn't really an issue, more of performance wondering if the 10" is enough, or if I should go 11". Front brakes are the 73+ disc BBP upgrades.
