We are building a pool this spring. We can't afford a slide this year, but plan to put one in next year. The builder says that we have to know exactly what slide we want to put in so that they can prep for it with the pool build. I've been looking at the Interfab slides, are there other brands that I should be looking at? If you have a specific brand & model to suggest I would appreciate that too. It's hard to narrow down the choices without actually trying any of them. The slide is for our two boys, who next year will be 6 & 8. (I'm sure that some adults will be using the slide too) Thanks for any suggestions.
