I think we are all coming from the same area, that you should be glad that you're having pass-thrus. As for the dulling of the blades or "rounding"; that is common with all types of fixed blades. Trust me, I used Thunderhead 125's for 2 years and in my own opinion they don't compare to the bone-busting power of Muzzy's. I personally don't know of any blades that can go thru the deer and dig into the ground, and come back perfectly sharp enough to use again. After they've been shot thru one deer, they become target blades.
