I want to get a solar cover and reel for my pool. The shape of my pool is curvy, Mt. Lake is the name of the design. At its widest it is 21 foot and it is 40 ft long. I know I will not find a solar cover shaped to fit, would an oval or rectangle 21x40ish work if I cut it? Also, I cannot seem to find a good reel that will also fit. I find 20 ft wide ones...Any suggestions?
