I had an -09 but I ran it with update kit.
With the update kit you had Bushing issues?
Your update kit was the new 1 piece bushings with the retainer caps?
I've had Zero issues of durability or "dialing in" with my 2 Timbersled skids.
So, as far as the skid "holding up"... a non issue.. and I've seen some BIG BIG boys 400 HP boosted Apexs as well as Dan Adams, Dan Gardiner, and Rob Hoff putting some serious Freeride hits and cliff drops on their sleds with the Mtn Tamers under them with no issues.
I have the update bushings in my Mtn. Tamer... no issues in over 1000 miles of riding. (I sold the sled and put the skid in my buddies Dragon... He put another 700 miles on it before I got it back from him... no problems with the bushings). I know that the first Generation Mtn tamer skids had some bushing issues that were resolved with the update kit.
Plenty of good info for settings on the T-sled. I followed the directions and took only a half a day to dial in the skid.
I would put both products in the same league for quality of construction....Both have rails made by the same mfg. Both skids use the Float Shocks, both skids require you to keep a keen eye on pressures in changing temps and radical altitude changes.
The big pluses for me is that the Timbersled Mtn Tamer is a coupling suspension. The coupling point and ride height are adjustable with the Timbersled as well as the position of the shock to tailor the progressive action of the shocks.
My lighter weight took a bit of thinking about lower shock pressures, but in the end, I had the ability to tailor the suspension for my needs.
IMO, a coupling design gives the rider more control on the higher hp sleds than a non coupling design.
The Holz skid is high quality like the Timbersled... no doubt about it.
I have ridden both skids under Dragons (the Alpha and the Mtn Tamer)... I prefer the Timbersled for it's deep snow capabilities and control in climbing.
