Are you sure about that? The way Eric at OJ explained it to me is that more cup actually makes the blade react as if it were shorter while keeping the same surface area. Like a dog ear standing straight up or folded over. I asked about a new prop they had with more cup (950 and 951) and he said it was meant for a boat that was having some clearance issues.
