I talked to Mr. Danny here and he'd mentioned Yamaha OEM black painted semi cleaver is a great prop in many applications. I'm running a 10.5 x 13p NREB and Stielleto Triad II. I read that I'd almost need to go up 2 pitches beings the props I'm running have moderate cup. So the smallest semi cleaver i can get is 10.25x14p, I'm just looking for some guys that know more about prop designs should I go with 14P or 15P?
