I have two gen 1 so I can't comment on how these mods will work on a gen 2.
I tried the wax fix. Worked well until we hit the low 20s temps, then the noises returned.
So I did the nylon bushing. I've tested it at single digit temps and its much better, but I can hear what sounds like tacky, sticky wax making barely audible sound...maybe on the plastic washers?? I need to clean off all wax and retest.
I've tried the Versa Lite strap and I really wanted to like it. I stretched it and broke it in, but it just ain't for me (sorry Carl...I really tried to like it).
Versa straps are great for sticks, but IMO, the stock strap that comes with the predator is better for gen 1s.
Maybe Versa are okay on gen 2...I will find out when my gen 2 arrives.
I also added 1 single Ameristep to the strap on my strong side. I really like having a step on each side. I use my top climbing step for my extra step on the weak side.
The only other thing I've done is to add a Lone Wolf strap for carrying. I sling it over my left shoulder which is the side I've always hung all stands...always to my left. With the strap, it carries nicely and is much easier to access when at stand height than having it in a pack...slip it off my left shoulder and hang it to my left. Hanging to my left works out well with the top climbing step being on my weak side and the Ameristep on my strong side. When I get to the tree with the stand on a strap, I'm ready to climb...no messing around with the stand in a pack.
My system is working very well for me.
