Right now i have a martin hunter 53 at 29 that likes 65-70 cedars. I cut mine at 31 in and taper to a 30in arrow back of point. I love cedars. I talked to people that said cedars fly alot better and are funner. It was true, i'll never shoot aluminum again these cedars fly to well i can't miss by more than an inch. OK that was exagerated but you know what i mean. They don't have to be perfectly straight either. I shot on into my new hay bale and hit a wire holding the bail tighter. It made a huge flat spot and really bent the arrow. I still shoot the arrow because it still shoots good. It'll be a squirrel arrow soon though.
