MSR Twin Peaks looks nice.

I've used a bunch of different stuff, bomber Winter Tent,
regular old tent, GoLite Shangri-La 1, tarp, and no tent at all.
All depends, who going with, where, what time...
Twin Peaks looks like a winner. I'm not totaly in love with
the Shangri-La 1. It does great in wind, it's just somewhat
of a pain to setup. Problem is is that if I bring it I
don't set it up on account it usually nice out...
I personally need to use it more in the snow to give a good
assessment.

So perhaps you don't think I'm making everything up, here's
a couple of trips from this year:

Favorite was to Echo Lake but that's not on the chick-on account.

I have some knowledge, but by not means claim to be an expert.
