Saddle with low profile/for low stack height

[Charlie193]

Looking for recommendations on saddles with a small distance between rails and seat. My current saddle (old Selle Italia slr xc) seems to be pretty low profile but I’ve been finding it uncomfortable recently. I got the longest dropper I could get away with so will need to replace it with a similarly shallow saddle. I’d prefer not to have to add shims and lose dropper travel so want to avoid saddles that will increase stack height.

In pictures the SQlab 611 looks like it has the rails pretty close to the seat- but I’m open to other suggestions?

I’m not looking at getting shorter cranks right now to decrease my overall leg extension, as it won’t make my saddle any more comfortable.
