Wow, look at all the ruckus I've stirred up!
lol This has turned out to be an interesting topic indeed. I once again have to thank everyone for the replies, your advice is very helpful.
The dilemma of choosing the right fins to ship with your boards does no doubt sound like a daunting one. For instance, I plugged in a MFC FS pro 20cm into my '08 K89 when flat water sailing, and I liked it much more than the Drake Natural. Thats on flat water though. My idea regarding crossover boards is that they should be thought of as the swiss-army knives of windsurfing. Meaning these boards are adaptable to anyones sailing style with the simple switch of the fin and sail types. The problem arises when people buy a board in this genre with the anticipation of the board performing well in all situations all the time with out question. As most of us hopefully know by now, it doesn't work that way. I believe that if a persons idea is to go with a crossover board, then they should be fully prepared to supply it with the necessary accessories required for the board to perform in the way they would like it too. I understand this and thats why I started this thread, to help steer me in the right direction.
