RE: Broadhead lenght?
I think the more cutting edge the better. These short little snub nose broadheads fly better than the longer ones, but the problem is even if you had 2 heads with 1" cutting diameter, a short head with 1/2" blades has only 1-1/2" total cutting surface as opposed to a 1" blade having 3" of cutting surface. The more cutting surface the more hemorrhage. The short heads are easier to get to fly, but with a little work, the longer head will fly too.
