This probably isn't the place to post this question but I couldn't figure out a better place. Anyway, I am in the market for a new sleeping bag for my fall elk hunts. Here is the regular scenario; I pack in by horse so space is a concern. The weather can be very mild(40's and 50's) at night or it can be down right witchy. We sleep in a wall tent the majority of the time, but I would like to get a bag that is compact enough for packing on a horse, but also in case I decide to "coyote" out during the hunt. I would like to keep my expenditure within $150 if possible, but willing to go a tad more if I have to. What experience do you all have with bags and what would you suggest?

Thanks for your input on this.

By the way I am 6'3" and about 240 lbs.
