As an experiment for 2016, I started mounting sheets in protective sleeves with custom pages with and without mounts. Even if you do not use a mount, the static electricity seems to keep them more or less in place.
I do not like Varios for large items now since some sheets are too tight of fit and takes some care to get them in the page. They also blend in better for me.
This was scanned with the sheet in the protective sleeve. I have tried without the page inside the sleeve or in the sleeve.

using the new optimizer tool.
If someone collected moderns sheets (what the USPS prefers you do), this is probably the best least expensive method - protective sleeves with custom sheets -- to do it.
