Depends what you want to do with it, imac a fuchs 32x12 works well, but can get a tad noisy if you let it rip. Another awesome prop is the 3w 31.5x14x8 3D prop, but again can get a bit loud. Another good choice is that engel 31.5x13 you saw me running in Shreveport, Jonas has it now and likes it a lot on his 260. Are you running cans and what does your plane weigh roughly?
