I will chime in as well because I have the almost identical setup right down to the Pentair Equipment (also 3x Pentair Magic Stream Laminar jets not listed below) and Viking Pool as you are putting in. The only difference is that I have an SWG and love it. water is much softer feeling, and I do nothing....nothing except test it and throw my stupid robot in once and a while. The fiberglass is so easy to maintain and clean. The screen logic system with the swg is awesome, I can log on my computer from anywhere and change my chlorine output. Look at my list of equipment in my signature and I'd be happy to answer any specific questions you may have.
Oh and get the panel that is equipped for the SWG, then all you have to do is just plug it in if you add it later which you can do yourself in a few minutes vs paying him or an electrician to come do it.
We were originally going to use Blue Stone, but decided to go with Stamped Concrete for the ease of maintenance, durability, installation, and in our area it was about half the cost of the natural stone. We actually used a wood plank stamp, and it turned out amazing. Our installer blew up a huge picture of our pool to hang in his show room. I will try to figure out how to post a picture for you.
