I'm fairly new to archery so I've got aquestion about arrow spine.

How do you select the correct one? I shoot a Fred Bear Quest. It is dual cam, 60# with a 27" drawlength. I have been shooting 2315 lite arrows. I'm having the draw length shortened 2" (was 29" will now be 27") so I'm assuming my arrows are all too long. Since I need to get the arrows cut down I figured I might as well buy new ones and start over. I'm also installing a whisker bisquit.

Thanks for the help,
Peter
