Ok.. I have my next colder weather quilt narrowed down to a phoenix .. Shot Adam an email asking about overstuffing a 20 deg, to make it a 10deg. Fearing the 0 would be too much, and worried about fitting a full sized incubator in my ula ohm 2.0 along with all the other goodies.. I only camp down to the 20s mostly.. But I use my hudson river in the house now full time, venting as required it's a 25-30 quilt.. So this being the case. I am thinking the o phoenix just might be the way to go..And being 3/4 sized saving me space in the pack and wouldn't it be easier to vent as well? Some body talk me into this...
