I had to smile when reading this thread, as we all have probably gone through the same process! So let me add my 5 cents worth, having been in your position not too long ago.
The main aim of starting out MUST be to have fun. It?s about knocking around in the surf, catching waves, getting your technique sorted out, feeling how the ski behaves on bumps, getting comfortable and being out on the blue stuff. And if it means hitting the surfski school for a couple pointers, go for it (you can?t go wrong with Dawid Mocke as a coach!).
Progressing too quickly from a ?beginners? boat to a fully fledged racing ski is going to kill the fun element, and frustrate the hell out of you. Though the one thing you will learn quickly is the remount!
Speed comes from stability. Having to brace every 4th stroke doesn?t do much for forward momentum. There are plenty guys running mid(ish) field on intermediate boats that are able to plough on when the conditions get tough, and leave the guys on tippier skis battling it out with the chop. Just remember that the sea is rarely flat.
The XT/Mentor skis are great intermediate boats, and they are fast enough to keep you interested, and stable enough to have fun. There is a huge market for them, so if you decide to upgrade, you won?t have any problems selling it.
Hey, test them all ? but I would go for the Mentor.
Btw, I think Custom Kayaks have just appointed a new agent in Cape Town (Sean Rice?), phone Mark Lewin to find out (031 312 1711). The Synergy is a killer boat, picked mine up on Friday:) That extra bouncy makes it hook up the bumps very easily.
