Sewn thru TQ for Winter?

[wwk10]

I have seen where if someone is shooting for comfort at 30 degrees, they may use a 20 degree UQ with a 40 degree TQ.

The logic is the UQ partially wraps around your sides and so the 20 UQ and 40 TQ get you to 30 degrees comfortably.

Can the same thing be done with a baffles UQ and sewn thru TQ?

I want to take a 20 degree baffled UQ and a 35-40 degree sewn thru TQ to get to 32.

My logic is:
The UQ is laid in a pristine shape so the cold spots from sewn thru matter.
But a TQ is bunched and squnched and wrinkled and balled up, so the cold spots are not as relevant.

So what are your thoughts on pairing a sewn thru TQ with a baffled UQ for WINTER use?

I've used a swen thru TQ in cold conditions many times. It works!

You'll want to think out your sleeping attire a little bit because even though the bunches work in your favor, there will still be areas of the quilt that are taut, like the area around the footbox. What works best with this situation, is a liner of some sort between you and the TQ. That will prevent/counter any casual leaks through the stitch lines. I've gotten into the high 20s using this approach and am fairly certain I could get a bit lower.

Disclaimer: I am a furnace when I sleep, so your results may very well vary.

Thanks Cannibal,
I think I will have a small foam pad in the TQ foot box and I always keep a wool cap and wool socks nearby.
I know its subjective, but what were the ratings on your TQ and UQ when you got into the 20s?

My sewn through quilt is a Shenandoah from Jacks R Better. It has a stated bottom-end rating of 40°F.
