Finally got some snow here and got the '13 Pro 163 out for the first time. All I can say is wow, this thing rocks! the snow was deep, 3+ feet of fresh, heavy SW Wa snow. Not the best conditions for a good break in. But the Pro handled it like a Pro. No broken driveshaft, no QD cogs missing, no bog, just awesomeness. One thing I noticed, coming from an '09 Dragon 163, is that the thing gets up on top of the snow really well. I've heard people say that about the Pro, but I could feel it rise right up out of the snow as soon as it started to get a little momentum. This thing was unstoppable. Anyway, very happy with the new sled.
