Greylock draft collar?

I am thinking about picking up a 3/4 length quilt and I am really liking the looks and the price of the Greylock 3. Does anyone who has one wish they had small draft collars like the Hammockgear Phoenix? It seems like the perfect way to ensure no gaps, but maybe the horizontal baffles take care of that. Thoughts?

I have the greylock 3 and used it for the first time last weekend. It went down to 30 and i was very warm with no draft isues.

Thanks for the info, TD. I assume there are no other responses because everyone is pretty satisfied with the fit.
