Summer quilt - down or synthetic?

[clutch146]

I know this topic has been beaten into the ground, but I'm wanting to make or buy a couple quilts to get me from late spring through early fall. Specifically, I would be looking at a 3/4 length underquilt with a 40-45 degree rating. Weight isn't too much of a concern - I'm mostly interested in compressibility. Does anyone have any photos of a PL or CS quilt next to a higher FP (800+) down quilt with those specs, in their respective compression sacks? I know that the down one is going to be lighter and smaller - I'm just looking for a visual on how much Thanks in advance!

I don't have any pictures on hand, but my Molly Mac Baby Orca (synthetic rated to about 40*) and my Hammock Gear Phoenix (down rated to 20*) have the same physical dimensions (45" x 52") and pack down to about the same size. I tried putting my Baby Orca into my Phoenix stuff sack and it occupied about 95% of the sack so it was just a tiny bit smaller than the 20* Phoenix.

Thanks WaffleBox, that helps - I currently have a DIY 3/4 length 20* 850FP down underquilt, so i can use that as a gauge. Now, the Baby Orca - that's an Insultex underquilt, right? So in theory, CS or PL would compress even further?

It is PPEF which is a slightly modified Insultex which packs down a bit more than standard Insultex, I believe. But I'm unfamiliar with how well Insultex packs down as compared to other synthetics.

Here's a synthetic Jarbridge 3/4 UQ rated to 25F next to size 10 shoes.
Note: This is uncompressed in the stuff sack - it compresses down to about 1/2 this size.

Check out the 1 minute mark in this video - it shows compression size:
