Jack,

 I thought I was pretty specific. (and evidently I think this is a problem
or I wouldn't have posted)
The information included:
    - size of strip (12.5")
    - lateral location of strip  (inside edge is 24" from root)
    - angle of strip (leading edge is displaced 7/16" up)
    - stall speed results (+14 knots)
    - stall handling results (nice strong buffet prior to stall with no
rolloff at max elevator deflection)

Not included are these other facts:
    - yes I had an incidence problem of .3 degrees.  that's been fixed
    - yes I had a wing contour problem.   the only one I know about has been
fixed
    - tufts show an even progression of the stall from the root to the tip
    - at strip incidence == wing incidence I still have a sudden rolloff.

My question is:
    - what other configs should I try for the strips that would have less
impact on stall speed
but still solve the handling problem? e.g. width, relative width, angle,
lateral location
