steel force 85's

[kt]

Well im am pondering a switch in broadheads, not that muzzy hasnt been close to perfection but in 6 deer i have never seen a drop of blood until i was within steps of the downed deer. A couple people including my friend at the pro shop have recommended the steel force 85's as they are near in weight to my 90 muzzy's. They cut on contact have four blades as well but the two big ones are serrated! i gotta say they look bad ass, on the down side they are a little longer than the muzzy's, maybe a difference on my little 27 inch arrows? i dont know. and they are 23 dollars per 3! wow
so im curious if any one likes them, do they fly where the field points do and how are they on bone?
thanks
