Which Board?

Hi again, Recently got back into the sport after 10 years?!!!(Got married, kids) Equipment has changed so much. I'm still trying to shake off the cobwebs and taking tuition and practice at a local windsurfing school on west coast of Ireland.
I decided to start getting some gear together again and really interested in CA boards but not sure which one to get, so maybe someone might help. I weigh 82 kilos and 178cm height . Living on west coast so its coastal and can get choppy. More interested in blasting. Intermediate level (gybe, waterstart) but would like a board that I can progress on. Help, it getting a bit technical.
