Hi guys, sorry you probably get these questions all the time but I need some feedback.
I'm a total beginner and I'd like to get started in Cat sailing.

First off, I live in Finland, Scandinavia, and the only brand we have available here is the Hobie Cat.
Secondly, Cats are extremely expencive here and there are virtually no second hand marked.
There are a few old Hobie 16 out there, but they are few and far between.
New prices i US $:
Wave $7000:-
Twixxy $8200:-
H16 classic $12500:-

My only realistic choíces would be a new "Wave" or "Twixxy" or a second hand "16"

I'm 183cm/95kg (6'/200lbs?) and plan to sail 50/50 with my girlfriend and my friend, hardly ever solo I guess.
(Girlfriend is ~110lbs and my friend is my size, ~200lbs)

Which boat should I choose for good speed and flexibility and why?
(I have been seriously interested in the Wave but it looks so simple and "toyish". With the prices over here I'd really like to get a boat to grow with, one that doesn't feel slow and boring after the first summer. Is the Twixxy next step up from Wave? It looks a bit longer with some more features...perhaps a good choice)
