Exactly.... we need a basic reference table that puts Stanwood quantities into a useable perspective of inertia moments for various combinations.... also... X amount of SW against R Ratio for Z amount of Front Weight yields a basic relative total MOI of some amount on a scale of for example 1 to 20. Point is,,, we dont really need exacting numbers to describe the amounts of MOI in an action... we really need something more on the lines of <<light, medium light, medium, medium heavy, heavy>>. This could be integrated fairly easily into Stanwoods existing system Doing so would allow for Techs to build into an action rebuild various amounts of <<inertial heavyness>> for differeing amounts of static balance, Strike Weight levels, and Ratios. All this done... it wouldnt be tooooo much of a stretch to find a method for bringing action compliance into this figure, in the same general sense. RicB > "Don A.
