Getting all of my ducks in a row for the swim season and I'm looking to purchasing a lighter weight solar cover and some solar saddles. I found the ones at the link below, which look incredibly convienent but I'm wondering whether or not they are safe for my pool rail and walls. Thoughts? Do you think these particular ones might cause buckling issues or anything? I could not find them anywhere else except this one seller on ebay (who has a 100% rating). In theory, it would be nice to not have to attach them to the rail.
