I may get to try it come the week end, or near Rivington, the climb up to the tower is testing but do-able.
The main reason to go 1x10, is I want to do some local races next year, done a few this year, but I wanted to lighten the load and certainly didn't need triple at the front - everyone elses bike is some superlight carbon its seems, with my budget I am stuck with alu for now. If I can get it below 25lbs I would be happy.
Also intrigued how I will get on with 1x10, as I reckon my next purchase would be some CX-Rigid29er type, with hydraulics and 1x10.
