There are four primary parameters affecting your fore/aft balance which need to work together to achieve your optimum neutral position. These parameters can be adjusted or modified, by an experienced boot fitter who understands alignment protocol, to match your specific needs. These parameters are Ramp angle created by the boot board and footbed inside your boot, Forward lean created by the boot cuff, Delta angle created by your bindings stand height differential, and the binding mount position on your skis. Setting your forward lean to "remind" you to get the pressure off, may not be the most affective strategy.
If you do some searching here on Epicski you will find multiple threads on this subject or you can also learn a bit more at www.snowind.com and click on boot fitting and looking around. If you happen to ski in Tahoe area, look me up and we can get you dialed in both in the shop and on the hill.
IMO...More forward lean will have no affect on lateral edge engagement, the uphill edge will only be engaged if the hips did not move across the skis during extension to release the edges.
