Hey folks,

I really appreciate the feedback. Ya'll guys know your stuff! Im either going with the Marmot Arroyo 30deg.(down) or the Mountain Hardware Ult. Lamina 32deg.(synthetic). Wight difference is about 4oz. Either way Im picking up a Seierra Designs Baffin Bivy for extra protection. Anybody have opinions on these??

A few last questions...A)I've been told that synthetic doesnt last as long as down as far as durability, retaining warmth, etc. Ive heard it loses its loft therefore loses its warmth quicker than down. Is this fairly true in ya'lls experience for those who've used both? B)Does a bivy add any warmth to a bag? It would seem that it would half to add a little. If so, what kinda of increase are we talking, 5deg? 10?

Thanks again for the feedback, ya'll rock.
