The link I have now is drilled 5" pin to pap(under ring), mb strong. I drilled it kinda strong thinking that it would be a weaker piece. I took the cover to 2k + snake oil, still just a bit to strong. I do have a higher rev rate, 17.5 mph at the deck. I've ordered another one and plan to drill it 6" pin to pap(high above fingers), mb close to track, hopefully that will work. Thanks for all the suggestions!
