FCS Mark Richards fins (3 fin set)

Hi,
FCS has two sets of the good öl polyester Mark Richards fins which I really like because they make me think of windsurfing in the 80's
(YeAh!). They have a twin fin set and a tri fin set.
Now I 'm a beginner, I've got a 7.6 Impact boards surfboard, my weight is 80kg (160 pounds) and I wonder if these fins are a good choice? If not, which fins would you encourage me to purchase?
Thanks a lot!
