I too saw this tent and will consider this when looking for my next tent.
My current tent I purchased from REI in the close out sale section. Used it this summer and I am happy with it.
A Big Agnes Wyoming Trail SL2 looks like it has all the features you are looking for except the pole length which is 24". I lucked out and found a sample unit on their website for $299.00. the only thing I could find wrong was the color coded tent pole webbing was sewn in the wrong place. I had been looking at the Redverz Series II Expedition tent but did not like the fact it was not free standing. After setting up the Wyoming trail SL2, I think it is going to be just what I wanted. The vestibule is huge.
and it is a free standing tent.
