I will still stand by the DuBro Nylon gear on the VF Edge if you ever even think you'll come in hard. I just can't believe how much that gear will take using four nylon 1/4" bolts. Check out that rough looking 3-pointer landing video back in this thread somewhere. I've flown the Edge on a few grass fields now too. Smooth as butta.
For those using the 91FX I found my perfect prop. 15x6APC.
