Matt,

Would feathers hold up through the WB ok? I'm just afraid that they would be torn to shreds and I would be re-fletching more than I would be shooting.

The Easton Shaft Selector chart is recommending arrows with a .340 spine (or there abouts). Can you explain a little more how increasing weight in the front and decreasing it in the back will soften up my spine?

As for the MX-4s, those are just a thought, I really haven't done my research into which broadhead I want to shoot, other than knowing it will be a 125 grain fixed blade. I've shot and liked the NAP Thunderheads and Muzzy 3 Blades before.
