Good begineer board for me and my kids?

I have had a home on the water since 2008. We spend all summer there. I have been slalom skiing since I was 7 and am 43 now. I have 3 kids 6, 11 and 13. My 11 and 13 year olds are really good wakeboarders. We went to Costa Rica 3 weeks ago and got surfing lessons and all 3 of us just loved it so we have decided to take up wakesurfing. My current boat is a Tige 24V and it throws a real nice wave without even using ballist bags but I plan on buying a few anyways. So my local dealer sells Ronix. I am thinking of buying the Cortez because even though I know that the real surfboard constucted boards are nicer with all the kids that will be riding the board I think I need one with the compressed construction so it will last.

Once I find out how much I like it and if I get good at it I can purchase a traditional construction wakesurf board for myself and only use it myself so I don't have to worry about damage. So what is the consensus on the Cortez? Also any other suggestions on a real good durable beginner board?

Thanks,

Chuck
