Helllooooo

Ive been reading over these forums for awhile now, But never got around to joining. But ive got a few questions That ive stored up if you dont mind answering..You'll be banging your heads with some of them (not that question again)

But here we goo
1) The first board - Ive been surfing about 3 -4 times now on a Swell/ Foam board. depending on the surf I can catch most waves into the beach, Standing up is 50/50 and so is falling down. However the only time i can surf is weekends, because by the time I finish work, all the Hire shops are Shut

So Im not rushing into this, I want to surf but honestly cant do it as much as I want to without my own board.
Sooo, Im a skinny lil guy, Im around 5'9 and weigh 9 stone...ohh thats 126 pounds for you guys across the shore.
I come from Cornwall, So i might as well take advantage of the surf around me right...
This is a board to last me awhile, it not so much a learning board. So am i looking around the 7ft mini-mal area?
2) Transport - Ive got a Saxo, not a Camper van

3) Use the Surf - How can you guys determine if they surf is going to be good, I had a 4 day weekend last week and was hoping to surf, the wind was realllly high. But You didn't even have to be Jesus to walk on the water those days, STUPIDLY Flat! So how can you decide if its a beach day or not...or do you guys use faithful google?
Anyway Ive blabbed enough

Cheers!
