Looking side by side of the bme and menz prop I have, they look almost identical, except the bme is actual length, the one I ran seemed like more of a load than a menz, it wouldnt turn up the same as a menz, thats just my experience though. Also this past weekend, we put a new bme 27x10 on my friends DA 100 with stock mufflers, and it would only pull that prop at 6200, motor broke in, and only about 75 degrees outside.
