No... but I do know they use the "C4" construction in the butt, the same as the 5K series. I had a 5K3 and the feel of the hit was great... but the predator shafts just aren't for me. If you like the Blak series, you may want to look at the 5K3 as it is also ebony with micarta inlays... a little less fancy looking I guess, but same construction... and may be a bit cheaper. Hope this helps.
