hi there, if i was you id opt for 525cc, just a perfect size! last year i had 340cc overs from a 32b and now a 32e-f, but i def know what you mean, there not that big really, id love mine to be bigger. Maybe in a few year i may get mine changed to a 525cc, which would give a good size, prob a g cup. So def opt for 525cc or even bigger if they,ll let you X
