Thanks everyone for taking the time to comment.
I have been doing some research on all your suggestions and it appears from mag reviews etc that all sails you have suggested here should do the job very well, so I will just pick the most versatile where I can have 3-4 sails (say 4.7, 5.3, 5.9, 6.5) sails and just run 2 masts if possible to cut down on carrying so much gear (and the expense)
Thanks again for all your input I really appreciate it, it has been 3 seasons since I have had to research before buying a quiver, so your suggestions have cut out a lot of hard slogging on the net and reading glossy brochures full of marketing rubbish (you know, where sails are so balanced this year compared to last year that they can sail themselves

)
Cheers, Adam
