Make sure you can take that basket totally off, or self-belay may be very hard. It could be that the basket is so small, it will sink in anyway; I'd sure hate to find out on a 45 degree slope. But if the basket is so small that it slips easily into the snow, what is the basket for?
I've got a BD whippet, and my biggest complaint is that it is hard to get the basket off for self belay.
