You might check out the forum called boatertalk. There are a lot of eastern boaters which might be more helpful. I used a sit-on top many years ago, and loved it (I never ended up a kayaker). But it seems the ducky (IK) has taken over the non-hardshell market. There are some folks hucking huge with duckies, so you can go all directions on them, but I don't think they track well in flatwater.
