what is she riding now, and why does she want a new board? ie what features is she looking for? more pop, more speed, nicer graphics?!
I think the LF Luna is a great all round board - I rode one for several years and liked it a lot. I tried the ronix coy once and thought it was a really easy board to ride - really predictable and easy to ride away from tricks. Not the poppest board I've tried, but still more than enought to ride well.
Re the melissa, I tried it recently and I loved it and hated it - just different parts of the ride! It was really really really poppy, but because it's a bit flexy it can be a bit unpredictable. Really soft landings. can be a bit skatey and loose when you're not on edge though. I also rode it with fins and couldn't get it to unlock from the water to do a bs slide for the life of me - it was stuck there like glue! so yeah, lots of ups and downs. I think without fins I might have loved it!
