Hey MJPOWHOUND - Living in Summit, I've probably run Tenmile over a hundred times over the course of 15 years. The middle section from Officer's Gulch is never more than Class IV on the easy side at any level. Every drop, you just go where it looks like you should and it goes pretty easily.
I'd call the section upstream of Copper Mountain (Upper Upper) mostly Class III+ with a couple sections that feel more like Class IV. It is, thus far, clear of wood for the year. That said, it's pretty easy to drive down the creek and hike down in a few spots to scout for wood, as I've done in the past.
