A classic platform. Minimal difference in the height of the platform between the heel and the toe. Picture it as a block of wood 6 inches deep. Now, it makes no difference at all whether that block is to stuck to your foot or stuck to the footplate, and it being stuck to the footplate would be no different than C2 having decided to set the footplate 6 inches further back from the cage than it is now.
Do you think your drive would be longer if C2 had chosen to place the footplate six inches further back from the cage?
You may get your shins vertical, but they are vertical six inches further back the rail than previously.
(Thinking about it, given the angle of the footplate, you likely shift the whole thing back 7/8 inches)
A slightly higher heel than toe would minimise heel lift at the catch - if that's a concern but likely shouldn't be - but a very large discrepancy will really, really pervert mechanics.
For the love of God, I really hopes someone else chimes in to put us out of our misery.
