I shoot indoors inthe winter time at the local club(It is about 20 yds.) and I was wondering what size aluminum arrow to use. I shoot a Mathews Q2 set at 55 lbs. I have a 29 inch draw and I currently shoot easton lightspeed 400s that are 29.75 inches with nock and tip. I was thinking of gettig some Easton X7 Eclipse's in size 2512 (30") with 1.75" feathers, "G" nocks, and a 150 grain bullet point. I was wondering if that would be the right size or not.
