Herings good top end high slip #s at lower speeds.
Im running Mercs new 16.5x 38 @ 18 Degree rake.
1200 Hp rated and came with a year warranty.I have turned 40 pitch herings 500 rpm more with little top end gain.Just depends what your looking for.I like the warranty.

You should contact Brett at BBlades. 20% slip is terrible. He has our 6 blade Herings at 8%.
