Huh???  That's exactly what Servotronic is set up to do!!!  It gives you
good assist at low speed and tightens things up at higher speed.  

I agree that the unmodulated rack does have a pretty good balance ...
but no matter what it is a compromise between the characteristics of
good assist for slow speed and good feel for high speed.  Last year I
did dig a bit into what it would take to "chip" the Servotronic to
change the assist curve ... I was hoping to find analog circuitry in
there, but was disappointed to find a microcontroller ... which would
mean that I'd need to reverse engineer the thing to make any changes ...
or create my own hardware ...  

I'm fully sold on the benefits of the Servotronic and would never even
think about disabling it or going to a non-Servotronic rack ... but I
would imagine that converting to the Servotronic setup would be pretty
expensive, not likely sufficient return for the investment ...
