I agree with you there. My swing keel is not that heavy (Mirage 5.5m) but the upwind performance is not great. Another trade-off. However, the low or neutral weight CB designs (Bristol, Tartan) I have seen really work well in shallow waters. I sail mostly on Pamlico Sound which has a lot of tricky, shallow spots that keep moving around. I run aground quite often but all I have to do is lift the keel a little and I'm back in the game.
