I installed a set of these on my Ferris the other day and didn't notice any difference in any rpm loss whatsoever at blade engage or wide open throttle. These blades rip! The first thing I noticed immediately was how far clippings were thrown. It gets rid of them and right now! I am won over by these blades. Good job Oregon
Conservatism is about independence and self-reliance.
Liberalism is about dependence and reliance on the enlightened few who know what's best for the masses.
Firearms are the equalizer.

Failure's hard, but success is far more dangerous. If you're successful at the wrong thing the mix of praise, money and opportunity can lock you in forever.
