Just go Isonic 155 and 9.0 freerace sail and you'll have fun. Went out on my F-148 and 10m sail yesterday and had a blast! My windsurf buddies couldn't believe my planing in 8-12 knots!
WS Flare is the same as pivot Gybe in my book. You should join a club as you can learn many tips on modern gear, else read magazines on how to improve ones sailing ability. Otherwise time on the water is the other solution!!
