I'm not sure your premises are valid. I've been using a mesh safety cover for years and this season was the first time I've ever had algae in the spring--and that's mainly due to 2 factors: The excessive amount of rain we had, and...my neglect of the pool until mid-May--I normally start the opening process in mid-April, so it had a month of warmer days with no chlorine.
If you live in a typical northern climate, where winter means snow and ice, you'll probably find the mesh easier--water doesn't pool on it, and it's much lighter to handle. When your water temp is below 50 degrees, you don't get algae growth, especially if you prepared your pool water for winter. You don't actually NEED a cover in the winter--it mainly keeps leaves, twigs, junk and small animals out of the pool. And, of course, prevents people from falling in the pool.
