does anyone own or ever tried the columbia reactor with the Omni-Heat thermal reflective lining.

I was thinking of getting one but wanted to see if anyone had any feed back on it. if not i would love to here feed back on your favorite sleeping bag. maybe i should go with down instead? My goal is to try not to buy an UQ . i live in south Mobile Alabama and our winters aren't that cold but then again i have never hammocked below the 40's but i would like to hammock in the 20's. is this possible to do without an UQ and not freeze my bum off with a good sleeping bag?
