I bounce back and forth between those two sizes. I'm not too picky about wheelbase but I've become quite a stickler for the nose and tail being big enough. I like companies like Quasi and FA that are doing the real squared noses and tails, but I can deal with it being rounded as long as it's roomy enough like an Anti-Hero or something. I recently set up an 8.25 that was really tapered like a football shape and I couldn't deal with it. The nose and tail felt tiny even though the board itself was still an 8.25.
Same here, prefer bigger fuller shapes for my 8.25/8.38. WB can either be 14.25 or 14.3x. I can't stand tapered/pointy shapes.
Thing is I like 8.3s with both WB, super rare to have 8.3 with shorter WBs tho, on average.
