Should I stop whining about 2" at 20 yds.?
2" @ 20yds would have me kicking the dog!
How are your arrows impacting the target at 20yds? It sounds like it's taking too long for your fletchings to stabilize the arrow. Just guessing by what info you've given I'd say you may have a spine issue. Do you notice any fish tailing when you shoot?
Do you have any other arrows you can play around with , like maybe 2314's or 2215's?
