Hi Dave,
I might be going off my rocker a bit here. You could, off course, say that I'm not tracking you well, but honestly, I'm not sure what the issue is.
We all want neutral boats. We also build them to our purposes, whether touring, playing, racing, or whatever else. We all work with what we've got and try to get it better, but to each his own. Balance is the number one issue. From there the options are legion and depend on what your boat is doing and what you want it to do.

PS My seat isn't as fancy as yours. (A more pliable closed cell foam and velcro tabs)

: I have also installed seats that are movable on the fly. And I discovered
: once I have gotten the seat positioned I never moved it. So its only value
: is to adjust for mis-loaded cargo. Adding a fixed skeg to a weathercocking
: kayak is the lesser of evils. It will balance out crosswinds but at the
: price of added tracking. The best answer I have found for touring is a
: kayak without skeg or rudder that is wind neutral, tracks well level, and
: turns on edge. This combination does not have a lot of rocker so touring
: speed (or long term effort) is good. A correctly timed knee lift will take
: care of almost any course correction without disrupting paddle cadence.
: Adding a little more rocker will make the boat more playful (easier to
: turn) and better in rock gardens and in surf at the cost of lowered
: touring speed.
