Well i changed my mind once again and went and picked up http://www.rei.com/product/763728, and i really have to say its a pretty nice bag for the money. I played around with it last night and took a nap on my back porch, it was 17f and with only jeans and a T-shirt (socks also) on a sleeping pad i think i could have some what slept comfortable. Im not going to lie and say i couldn't feel the cold but for a bag rated to 40f it was pretty impressive the thing compresses down good and weights in the area of two pounds all in all i would give a 8.5 out of 10. Just thought i let you guys know about it. I really did think about going all out and spending 200+ on a bag but i really don't think i need it, im a pretty non fussy sleeper and up untill now during the spring and summer have been using nothing but a sleeping pad and survival blanket to this will be a big step up.
