That was painful to read ~ I know that feeling of being over-biked for a trail... I had it several time on the 950. As you're figuring out, once the momentum is gone... it's ALL OVER. Gotta turn around and try again. That's what happened on the Louie Lake trail, and what happened at Big Windy when I smoked my clutch.
You'll like the TKC's, they'll give you considerably more traction. Can you put full knobbies on it? That was the saving grace of the aftermarket rims on my KTM, was that I could run the full-on dirt knobbies on it, which made a significant difference.
