Careful hanging the seat from the gunwales, especially if you're a bigger guy. Piragis has replaced a number of Bell hanging seats with floor mounted sliders after the brackets have broken or stressed the side walls of the hull (and Bell adds an extra layer of cloth in the center to support the seat). Generally a problem associated with paddlers of 200# or better. You can buy a complete floor mounted sliding seat and bracket from Wenonah.

I don't understand the difficulty people have with straight tracking hulls; much easier to learn to turn a hard tracking hull than to make a wandering hull travel straight efficiently.
