Bushing problems are from earlier M's. Tried to save wieght. Bronze and heavy now, but last.
I like the Simmons (old style) in powder on my M sleds. Least amount of drag and snow build up of any ski ever. Second best, stock '05 and '06 Powder Special skis.
I always return to stock single skag skis in the spring though. The AC front spindles go through a lot of camber change and can lift the short Simmon skags off the snow.
Early in the day, when the snow is still hard, you can lose the front end 'cause of this. While crossing a side slope to get to the north side, this has 'caused a few scary moments for me as I try to slow down before the trees at the bottom LOL.
