Your design is very similar to the one we built last year. We put two led bubblers on the sunshelf and two led laminar deck jets. The deckjets are never used and was a waste. I think if I had four jets together it may have looked nice but having two at opposite sides didn't work out too well. The bubblers on the sunshelf I keep on a lot because I like the way it sounds and looks.
Two things I'll point out. If you put a basketball hoop on the deck in the middle of the shallow end you won't have much room on the side with the steps and it will affect the game. And if you want a volleyball net you will want to put it on the deck right before the sunshelf starts, but you might not have enough room in the shallow end to play. If I was building your pool I would forgo the four deckjets which may be as much as four thousand five hundred if I remember correctly how much my builder was charging) and enlarge and widen the pool so basketball and volleyball will be better. My kids and I play those games all the time and I suspect your kids will appreciate a wider pool much more than four deck jets that will probably annoy them more than they will enjoy them.
