David,
Did you have any problems with the UBARs causing misalignment, when spin testing? They were fine without the UBARs, but with them, they wobbled badly. That' s why when I switched to carbons, I went with the Muzzy' s and the Wasp. TH' s are fine broadheads, I took many deer with them on my aluminums. Wish they would' ve worked on the carbons for me.
