I like mine I shot a doe with one this year and it was a complete pass through but did hit her just behind the shoulder and it isnt too hard to get a pass through there.
I agree with TNDeerGuy the 400's might be too weak. I shoot a brute HP with similar specs and my 400's shoot fine with a field point but once I put a broadhead on they started getting goofy. Switched to the 330's and they shoot pretty good with a broadhead.
I shoot 29 inch 330 bloodline realtree camo with 100 grain thunderheads helical fletched with blazers through a Carbon Element @ 70 lbs. Extremely accurate arrows that look great and are pretty fast and hit like a hammer.
There good arrows but you might wanna go to a 330 spine like said above. Another good arrow in that price range is the Beman ICS Hunter. Which Easton Owns Beman now anyway...lol.
I shoot the 400's and my bow is in the 60-65 lb range. Great arrows... the first two deer I killed broke the arrows because one hit the front legs and the other hit the spine and the deer rolled over on the arrow. However I am now using an arrow that has passed through 4 deer (3 recovered), stuck in the ground a couple times, and went into a 1 inch thick OSB board. Same broadhead and arrow and I keep a tally of kills marked on the vane. Ready to kill another deer with it. I got the cresting tore off and new vanes glued on by Matt Eddie (Energy wave archery) up in Hermitage. He didn't charge much to do it to a dozen arrows, I'd recommend it
