Familiarity: I've used it once or twice and have initial impressions
Just took my 188s out for the first time and was completely blown away! Unbelievably stable at speed, with great carving abilities once you get used to the camber in the back seat. For having so much rocker and width, the tips were easily maneuverable and didn't knock around nearly as much as I thought they would. And boy do these things love getting in the air! The stiffer tail just grabs the landing and plops you right back into a stable position. Skied 6"of soft stuff and some deeper crustier stuff for a few turns and didn't have any issues with flotation or control. Couldn't imagine anything but great floatation and planing in deeper snow.
My only complaint is that they're not exactly nibble and really had a hard time in the bumps even for a super wide powder ski.
I can honestly say my first day out on these was my best performing day on skis. It felt like I was driving a Baja racing truck. Just wanted to go big and fast.
