I just bought a reel for my AGP - 15round. I'm so nervous to drill the rails so I'm considering posts on either side. The first pic shows that I modified the bracket with a shim glued in (it's designed to have just one bracket for the support base to slide into. I used to brackets turned upside down which lifts it over the support beam of the pool. So if I do decide to drill the rails at least I'm on the strongest and widest part. should I worry about drilling it?
