We have a Rocky's Roller to roll 80x16 and it works fine, but the problem is that we can't find a 75x16 cover, so we have to connect two 40x16 solar covers together. The connection isn't always even, so the second cover sometimes starts to bunch. People have sat on the roller and not broken it yet, but it's not a good idea.

Guess I should have been more specific. We had a reel and it worked fine, as far as a reel is concerned. The problem was the free form shape of the pool caused very uneven rolling. When we placed at the end, it was such pain we never used it. Two years ago we purchased a new clear cover and attached it in the middle. While this worked better in rolling up the cover it meant either we left the reel over the middle of the pool (really ugly) or moved it off to the side (not a one person project). So my question was referring to a product called a solar roller cover stick. I am wondering if these do work and are easier than a reel for an irregularly shaped pool.
