I think the things, (some possibly silly), that have put me off are the fact your standing, (sitting on a jockey console seems half the fun of ribbing), plus I quite like the idea of an open bowed rib, (mine isn't), and when going slowly, trailing your hands over the front of a boat is a nice feeling, and finally you've lost half the open space of the rib..
Tho will probably regret it next year when looking to upgrade, and finding nothing decent under 8k..
