Webfeet...love the name. Sounds like about the right pump size and I would go for a 2 speed. I know a lot more now than I did 9 years ago when I got my inherited pool redone. Can't knock the Hayward superpump...9 seasons now. One thing to consider, enclose the equipment in a poolhouse or something if you can. Keeps the sun and elements like rain off the equipment. Maybe that's why my stuff is lasting so long.
