These are my everyday ski too and I find them very versatile. Great for all but the deepest or hardest days. I took off the system binder and put on a pivot 14. I like the way it skis much better. I didn't think about moving the mounting point back but, there is a standard mount point mark on the ski like a non-system ski has.
I think they ski powder great, the only time I get in trouble with them is coming off a drop into deep snow, sometimes it gets buried a little. they also perform well on all but the most boiler plate ice but, that may be my shortcoming.
