I'm looking to buy a dozen new arrows for the Parker Wildfire I just bought. After shooting the six I have, three Beman ICS and three Easton Epic, I prefer Bemans. Both are 340 shafts, but the Eastons are 29" and the Beamans are 30". The Bemons tended to be better with the 100gr Thunderheads I have. I'm just looking for advice as to the set-up of the arrows...My bow is set between 60 and 63lbs and I have a 29" draw. Both arrows with broadheads were fine in the rest, draw and everything else.

These are the arrows I'm looking at.....
Beman ICS Venture
340
2" straight Bohning Vanes
30" length
100gr b-heads and practice tips

Would the size different between the 2" vanes on these and the 4" vanes on what I have make that much a difference and would it (potentially) be for the better or worse?

Thanks for any help!
