The system on my boat I think is the best. Its the kind with the strips of webbing that run the length of the slot with a fiberglass rod backing the laces. I've had all three systems on the boat and this one is the best. Just make sure that the webbing ends are reinforced because they will fray there. I've got pictures of the system on the f20 forum somewhere.
I cant see the pics on your I20 forum post. Can you repost them ? Again, something made or something bought?
