In fact, this point makes the 2:1 ratio questionable as a guide.  I 
could probably come up with a kayak and gear arrangement that 
achieves the identical balance with 1:1 weight simply by judicious 
choice of which gear goes where.  However, it would not necessarily 
snap around due to rotational inertia about the vertical axis.

2:1 may only apply if we are rigorous about placing the load in a 
certain way - massive items near the cockpit and light objects near 
the ends.  But then, sometimes ballasting with weight in the ends can 
have a useful damping effect on pitching.

I've been thinking of this on the weekend - if we rely on weight 
distribution to minimize need for a skeg/rudder, we risk goofing and 
not being able to adjust on the water.  If we rig a sliding seat to 
correct on the fly, we have simply replaced one form of mechanism 
that can fail with another.

Regardless of goofs, I know that my kayak needs slightly different 
skeg settings for wind on the starboard or port bow versus wind on 
the quarters.  Given the simplicity of the most basic skeg designs 
(rope and cleat rather than silly little sliders and Bowden cables), 
I don't see much point in avoiding them.  The skeg box's blockage of 
the stern storage area is a minor annoyance IMHO.

BTW, Nimbus (Rainforest Designs) kayaks all have sliding seats.
