Pierre Yves Leblanc and Robin Courcelles base out of Whistler and are AFT riders. They would have the Daddy models now. Robin was testing the Big Daddy last spring allready.
The new Big Daddy, Sugar Daddy, and Stomp models were designed with and for the AFT (Atomic Freeride Team) skiers.
The Stomp is a terrain park/new school freestyle ski.
The Big Daddy is for BBBBBIIIIIGGGGG mountain skiing. Helicopter access, really deep snow, steep, and fast.
The Sugar Daddy is a cross between the two. Someone not powerful enough for the Big would benefit form the softer and smaller brother.
The other three fat models, available now, are the 10.ex. Powder Ride, and the Heli- Star.
10.ex is a true all mountain fat. Great in soft, very good on hard.
Powder Ride is an awesome heliskiing ski. With the new Big and Sugar available, this one will most likely be discontinued.
Heli Star is ideal for heli and cat skiing operators' rental fleet. Wide and easy to ski.
Stay at 173cm for the Sugar. I would suggest you consider a more all mountain ski, such as the 10.ex. The Sugar Daddy works best when the snow is soft and deep, and can be quite tiring once the runs get skied out. The three to-be-released models are basically the full blown top end ski in the Ride line-up, like the Race 10.22 and 9.16 are in their's. The 10.ex will allow more freedom to ski the whole mountain in a given week. If you have guaranteed powder though....
