Well, stay away from the CWB, LF and HL boards. So far everything I have seen from them is SLOW. I haven't seen the new LF stuff, so not so sure there. The Walker Project, Shredstixx, Inland Surfer, Soulcraft Boards, Lakewakes boards, Phase 5, Calibrated are all boards we have tried out behind our boat and work well. Other than the inland surfer sweetspot, we haven't really tried any of the new IS boards, but they have the Squirt and the Mucus which are supposed to be good for beginners. Many beginners like the Lakewakes boards, because they are constructed well and Mark is selling at really good prices. Many of these boards are $600-$800 dollars and tough for a beginner to get started on.
A good phone call is to Mitch at CalMarineSports.com since they carry most of these boards and he has done a very good job of matching people to the right board. Mitch was with us when we did our big demo events, and when you do those, you get a good feel for what works for various people.
I don't think CMS carries lakewakes, but you can hit them on the web. Good luck and post pics of the new board and wake.
