No tuning issues at all Derek, other than coming up short speed at spec.(an issue we have not had with the Monster series). I will say they will whip a slightly underpsined arrow (chartwise) through the chronograph completely sideways though! Took a bit to work up an appropriate spined arrow at that low weight.

The bows we got in were way out of spec (timing marks) requiring a few to several twists in control & buss cable (as well as to deal with cam lean), and once put within spec- 4 shots the first bow had significant serving wear.. FOUR shots. Another lasted about 12 shots i've heard (wasn't around to see it myself) This is likely a sympton of poor harness/string, but also could be the cam profiles.Not sure yet cos I haven't messed with the bow since and I refuse to draw/chrono the 30" (I like my back and arms thank you very much ) Draw length ran about 3/8" long on ours as well, which for a PSE is pretty darn good!

I still might pick up a Xforce of some sort this coming year, but I'd like to get some more feedback over time on these cams before I put down the cha ching. That new rumored 37" 7.5 brace Xforce is more likely my cup of tea.
