This was mentioned in the Fin Whispering book . . . I am not advocating this practice . . . just asking . .
Preventing slippage with tight screws on plates stiffens the ski and puts shear stress on the inserts. If the front pair of screws were slightly loose but secured with blue-locktite (removable), it would reduce these affects on the ski. Is that a "step to far" or is that part of the ski tuning toolbox?
