11x14, 16x16, 16x20, 20x20 and 20x24 are the only sizes I print in right now from 35mm and 120 format. I don't shy away from 20x24s from 35mm negs unless they're really thin and the contrast filter needed is beyond #5 plus cold developer. I sometimes do 8x10 RC prints for snapshots for friends, etc. but for my exhibition stuff, I go 11x14 and above on fibre. I'd love to go bigger, but I just can find time to custom build a 30x40 easel or money to buy large rolls of FB paper in that size. I then start thinking of the matting I'd need to use for it and then building the frames and cutting the glass for it and I loose interest. Maybe one day though.
