I have put a ton of arrows through my hybrid over the last month or so and it is my first limb driven set up. Previously used TT and RipCord Ace. My thoughts, and remember I'm not a pro shot or tuner...
-Easy to install and set up
-launcher is pretty quiet, but does make some noise, a quiet day in a treestand at very close range might be bad.
-Launcher wear is real, and it can wear inconsistently. Wear does diminish after a hundred or so arrows, but I did readjust for height and centershot which seemed to increase wear again. Once I had it set up at centershot I installed a new launcher, which again wore down and it bugged me, along with the noise, so I bought a metal Hamskea launcher and filed it down to size and put felt on it so it would be silent and not wear. Is this necessary or a launcher design flaw? Probably not but it bugged me because I am pretty OCD about my gear.
-The launcher came up real early in the draw cycle (immediately) if set to limb distance spec on my Nitrum. Fletch clearance wasn't an issue, but I felt form inconsistencies or torque might be influencing the arrow if it was on the rest nearly the whole way off the bow. Again, is it an issue? I have no idea (inconsistent tears), but I decided to try to make the rest come up a little later (moved cord to nearly centered on limb), which is really now more in spec in terms of the rate at which it comes up than it was when 3 inches from the limb end.
-Hamskea customer service is great. I called a couple times with questions and they fielded them completely and mailed me my launchers and felt in short order. They are top notch.
Overall I think the rest is of very high quality and I have high hopes for it. I have some other tuning and shooting kinks I need to work out though before I can say it is the way I will be going. Better shooters/tuners than I will hopefully provide more info...
