Mt Whitney Zone Forums Gear Heads new lightweight 32 degree sleepign bag

Any one have any suggestions or recommendation for a good 32 degree bag that is as light as possible and compacts down very small?

I have a Hyper Lamia Spark now, but have grown tired of it's half zipper and I think it's worn to the point is not keeping me as warm as it used to.

So lightweight, compacts small, full length zipper (so I can open it up fully on warm nights). Hopefully not too expensive, but I've learned that I sometimes have to spring for the good stuff.
