arrow spine help.
I'm recently purchased a mission venture. I have it set a 66 pounds and have a draw length of 27.5 inches. My arrows are 28.5 inches long. What spine arrow do you think would best suit me.? I'm shooting 400's like the chart suggested but they dont fly great and paper tuning the bow has proven to be very difficult, if not impossible. Would 340s be a better choice. I'm right on the edge according to the chart, but i feel like these charts dont accomodate the newer faster bows. Any help would be appreciated. I've checked for other problems such as fletching clearance etc, and none exist. The bow also is pretty loud, i'm hoping a heavier arrow will quiet it down. While i'm at it any good recomendations for a new set of arrows. i like the easton epics, at least what i've read, but never shot them. Any good? Thanks Matt
