Hi for the first time and a few questions?

Hello everyone.
I have said hi in the "hi section" however I thought I'd introduce myself properly in the chitter chatter section. My name is Andy I live in Hampshire UK not far from the admin dude.
As of this year I have taken up surfing (transferred from Snowboarding which is quite similar) and can now see what all the fuss is about. I have been surfing about 6 times now and have taught myself to stand up and catch waves, which Im quite pleased about. I have a 7ft Rip Curl Mini-Mal which is a lovely board but I feel maybe a bit too good for me. It is a very light board compared to my friends 7.6 NSP which seems a lot heavier and sturdy.
I found riding her NSP I got to stay up for longer and catch the wave further up the beach. I was looking at buying a 8ft Mini-Mal which would give me a bit more stability and floatation especially for the UK shores, what do you guy's think?
I did notice a lot of guys/girls down Saunton Sands had longboards and where getting up easily, however I feel I would like a compromise as I do not have the room for a 9ft + longboard and also like bit of a challenge.
Any help and advise be greatly received.
Im 6ft tall, weight 13-13.5st.
PS whats the difference between a single fin and a 3 fin set up?
