I must say that i use only Ezzy sails 06:
4.2, 4.7 and 5.2 Wave SE
6 and 7 Infinity
Wave SE are the best sails i ever had for wave riding and the 6 infinity can be very pleasant too in a no cam figure and small waves conditions.
The 2007 have a different feeling, but when correctly rigged ( thank's David) should be excellent too ....
I'm thinking to the PA 80 for medium wind : 18/25 Knts and good waves conditions ( i'm 73 kg), so let me know your experience with this board ...
