Mad....looking over the posts on this thread I see and inconsistency in terminology that you are using and I just want to verify that it is just that, an error in terminology and not an error in equipment selection.
When you say you are shooting a 400g Easton Epic arrow, is that to say you have actually weighed the arrow and it comes in at 400gr or are you shooting Easton Epic 400s. There is a HUGE difference between the two.
If you are shooting Epic 400s with a 32" draw, that would put your arrow length somewhere around 31 to 31 1/2" in length. This arrow would be severely underspined for your rig and probably approaching the danger zone of blowing the arrow up on launch.
One more point. Easton rates their carbon arrows by spine (inches of deflection when a weight is hung from the center of the arrow with the arrow supported a specified distance apart...I believe this is 28"). Spine essentially gives you the stiffness of the arrow. Lower spine numbers mean lower deflection and a stiffer arrow.
An Epic 400 is a .400 spine arrow
An Epic 300 is a .300 spine arrow (much stiffer) and heavier.
Given the length of your draw, and bow poundage, I would expect that a .300 spine arrow would be about right for your rig.
I certainly don't mean to insult your intelegence, however the nice round numbers like 400gr and 300gr that you have been using seem more like arrow spine numbers than actual arrow weights.
Good point Redline. I just maybe wrongly assumed that someone shooting such expensive a bow would know that. Maybe not. If he is shooting 400's that could possibly be a reason for less speed. The arrow just flexes too much coming out of the bow.
GUess we'll see what he says.
