After much procrastination, a Bear Kodiak Magnum came home with meyesterday. I need to get arrows. Because I'm new at this and will destroy many arrows, I'm going with aluminum. I'm guesstimating my drawlength to be 25" (I'm 26.5" w/ a compound). At 25" the scale reads 45lbs for this bow. I'd like keep to keep the arrows a little longer like, 27", just for my peace of mind. Any suggestion what size arrow I should start with? Oh yeah,the required pics:
