Interesting, and I'm guessing you're in a more advanced run group?
I just was recently solo'd so I still have a long ways to go...
That said, I loved the grip on the NT-05's! The only time it was an issue was at Lime Rock when they were newer (~300 miles) and were a little greasy in tight transitions.
