My pool is brand new this year so we need a full install kit for the loop loc my PB recommended. I call poolcoversdirect.com... they are $1k cheaper than the PB. PB selling point is I save sales tax. That ends up being $28.00.
We had bluestone. It was hot also. It was great until the mortar started to get loose due to the winter freezes on Long Island. Nobody wanted such a small money job to re-mortar the joints. Just my 2cents.
