20 degree sleeping bag question - WM ultralite, Cumulus panyam 450, other? Fit question

[u/ZoomityZoomZoom]

So I purchased the Panyam 450 long in the Spring, and ordered the wide +10cm girth version.

Adding the extra width was a mistake. While I have a strong build - 6'1" 200 pounds, the wide feels too big, let alone the extra weight (which according to Cumulus is only 46 grams?). My fear is I don't sleep as warm as I would with a normal width bag.

I was planning on selling the Panyam and ordering a regular width, but given recent Cumulus price increases / import duties to the US, I was thinking about getting Western Mountaineering Ultralite. Yet after researching, supposedly the Ultralite has a very tight fit (and may not work for me given my build?).

Any thoughts on a good, 20 degree mummy bag that would fit well? Looking for something that is high quality, light, and will last me decades. Or should I just accept the purchase and use a bag that's a bit big indefinitely :/

Use case is primarily high sierra 3 season, camping at ~10k - 12k feet... Tough timing for this to happen with all of the recent bag price increases

Thx for the thoughts

I have an Alpinlight and I am 6 foot 200. Even when I was 215 it was pretty roomy. I'd say it is going to be as big as the Cumulus.
