Good Beginner Board?

This fall we bought a 2006 Moomba Mobius and I was wondering what wakesurf board would be good to go with it. Does anyone recommend this as a good boat to surf behind it? What is a good beginner-intermediate board that is also kind of a universal board for most people? Most of the people that will be using it will be about 6 foot or shorter and about 140-160 pounds. I am looking for a board that is good for beginners to learn but nobody will outgrow it in a year. One that is good enough for beginners to learn on, but keep using it until they become much more advanced. I've done some research and it looks like most people use the skim board style rather than the surfboard style, but I don't know which would be better. Any feedback or experiences are appreciated! Thanks!
