I've been looking for a spare prop for my RZ2 and came across a OJ 466 for a reasonable price. I have a 1235 and a 537, but if anything ever happens to the 1235 i dont think the 537 will be much good for surfing when i'm fully loaded. On paper it looks to be comparable to a 1235 or 1433. Does anyone have first hand experience with these props?
