Been reading here for a while, finally decided to sign up and do more than that!

I ordered a full size Winter Incubator from hammockgear.com, but after reading a few threads I seem to be doubting myself a little bit in my newbiness. I only have enough money to buy one under quilt, and I bought this thinking I can probably use this all 4 seasons. I am definitely confident in my decision to go full size, as less than half a pound isn't enough to make me want to go smaller, my pack has tons of room, and it's only 20 dollars or so more.

The only concern in my mind is wondering if it will be TOO hot for the other seasons. Since I've never gotten to actually try one out, is that a realistic problem? Do I have to worry about it being too hot at night? I can always get a 3 season instead and eventually buy a winter one, but my goal is to just buy one and use that as long as I can.

So what are your opinions, can the Winter Incubator work for me all four seasons, or should I get a 3 season bag and forget about winter for now?
