I'm shooting a Bowtech Liberty, 74lb peak draw weight, 28 inch arrow w/ 125 gr head. I was using the Easton 2314 Super Slam Select, 4" feathers, straight fletch. The bow was properly tuned, but had issues with field tips and broadheads grouping together. Ended up adjusting the sights to the broadheads. This year ordered another dz arrows from an online Co. They were also 2314, Super Slam (apparently they stopped making the select) with 4" feather, right helical.Just shotthe new arrows and the field tips and broadheads now group together. Did the right helical make the difference? Or was it the fact that the cock feather on the new arrows is at 9 o'clock instead of down. (I have a drop away rest so I would not think that would make a difference) And if you look at the Easton chart I should be using an arrow from Group J not I. I'm confused.[&:]
