I figured I would come back and update. I've responded on other threads about this, but I'll address it here as well.
I picked up an SS34 a couple months ago and after great experiences with the Hi-tek on my Elite last year, I decided to order one for my SS34.
The Hi-tek that I received is one of the new designs. Personally, I prefer the look of the old style but with experiences like what
@raisins and others had, I completely understand why they had to redesign.
I was able to make the new style work on the SS34. The string is not centered on the rubber stopper because when it is, I get cable contact on the carbon rod at full draw. As pictured is as close to center as I can make it at brace. It seemed to have been an improvement over stock in the felt vibration department. Any noise difference is hard to discern.
