my father has been shooting the slick trick mags for a few years now. He shoots a light weight of 50 lbs and a short draw of 27 in. He likes the fact that they shoot the same as his field tips but has also had a few shots without complete passthroughs also. This year he is going to try the original muzzy 4-blade with 1" cut. I think the longer angle of blades on the muzzy will help with penetration.
