Rick some of us just come down a level to let people understand on a lawn mowing level that the G blades in my 2 CENTS are well I would rather buy beer then put those blades on again. I do understand how they work and if people want to understand how they work they would ask you. You are very knowledgeable person this business and just on the home owner side of things I would keep it simple and stick with oems. I don't like how those blades clog under my deck I do not have the issue with my oem's and I do have a mower that turns 19,000 tip speed. Y waist your hard earned dollars when I have already done that? I just suggested in simple lamens is that stick with OEM'S. Ok and people read this post and take it for what it is. Just putting it out there that they are my opinion not up to par for the money. Hope this helps some on the leaning table.
