Jeff,
IMHO... Trying not to be biased... Promise...
First off, I don't think you asked about kiting... But it is a viable consideration... I have nothing against kiting... It's fun... It's different than windsurfing... They are two totally different animals... Kiting's the NEW thing... Till it becomes just kiting... As did windsurfing... Anyone who sees the best in the sports of either doesn't say it's JUST one or the other...
Kiting and Windsurfing are both major addictions to many! Every individual will have a different thing to say... I know windsurfers who claim to be over windsurfing and kite.. Some don't do either anymore... I know kiters who are bored w/it and feel they've peaked and are looking to the horizon or are windsurfing again...
If Rush were full, you'd be getting a WHOLE different response here first of all... When Rush died, windsurfing suffered a huge embolism... If it ever fills again... Look out! It was close and over a 100 sailors would be out there on any given windy weekend day throughout the 80's and 90's... It's mostly dry now... But it was close and consistent...
Windsurfing is an endless effort to improve... A guy in the Gorge (Jim Oaks) started windsurfing at 40 and is looping and throwing all kinds of old and some new school tricks that some of the pros are in awe at... He is one of the smoothest extreme sailors out there at the Hatchery (World Class Sailing spot, Hood River, OR)...
Windsurfing isn't the easiest sport... But it is unbelievalby satisfying when you try a trick (jibing, water starting, duck jibing, monkey jibing, looping, sliding) over and over and over and then finally stick it... No better feeling... It takes real dedication but I don't know of any sport that is more rewarding after hard work...
But kiting's fun too! Marty says it's super easy... And that it doesn't take very much physical effort... I'm sure there are differing opinions from kiters on this...
I thought it was pretty easy & fun, but you need to be more cognizant and careful with kiting... To be honest... You can only serve so many masters! I've kited, and have liked it when I did it... Windsurfing has remained my wind fix... There's WAY WAY too much challenge left for me in windsurfing... But I've only been windsurfing since 1978

... I plan on snowkiting for sure... And paragliding...
There are amazing numbers of kids windsurfing and Kiting in Maui and in Europe and in the Islands... It'll be interesting to see the next big thing that sweeps in and takes half of both participants from Windsurfing and Kiting... Some cutting edge sport that's seems cooler than these! But both have deep reward... I can't be too biased now, I don't want the UWA to have a two party system, or even three!!! he he... But I'd say, give windsurfing a try until you can pull off a successful planing jibe... Then ask the question again...
But if you keep up the sailing you'll be rewarded... Just like anything... It takes sacrifice for reward... It's just the HEAVY reward with Windsurfing is preceded by HEAVY sacrifice and effort... Effort that actually to me is rewarding in itself... If you Kite, the SAME thing... The important thing is that you are STOKED about the wind! ...
