Big difference in durablitiy between compression and real surfboard construction?

I have heard from more than one person that you have to be extremely careful on the surfboard construction wakesurfers. My local dealer sells Ronix and told me the Koal is a more enjoyable and easier board to learn on than say the Cortez. However I will be wakesurfing with my teenage kids and alot of there friends. How delicate are the traditional surfboard style built wakesurf boards? I have heard one drop on the dock and the traditional style boards can crack. Where the compression boards are very durable like a wakeboard. Seems to me I'd be best served using a compression style board for a few years to learn and then if I really get into the sport look to buy a traditional built wakesurf board. Am I on the right track?

Thanks,

Chuck
