If it were me.. I'd run the Chariots.. When it comes time to replace the petals on VF your looking at 120.00. Vs. 50.00 for the chariots. You wont see any power difference between the 2 on your motor. Dyno's have shown in the past that a good set of aftermarket reeds on stock cages are almost identical to VF cages on a stock motor. Hell, if you dig deep enough and you can probably find the dyno's on here.
