AKmud, I think the vast majority of us who shoots a long bow do so using a medium to flat/low wrist grip. That requires an arrow pass of between 1 1/2" to 2" above the dimensional center of the bow. If you're placing your arrow pass/shelf at the center of your bow and gripping below that then you're basically shorting your lower limb by a considerable amount even with same length limbs.
Think in terms of your limbs beginning at dimensional center of your bow without a handle (handle is added for comfort only). Concept here is to grip your bow close to center as you can to apply the same amount of pressure to each limb as you draw your bow. NO MATTER HOW YOU GRIP THE BOW! And of course, arrow pass/shelf is then placed above the bow hand.
Another advantage to equally straining your limbs using the correct grip is equal limb mass distribution. Makes for a much smoother shooting bow with less hand shock.
Yes, you probably can equally distribute limb strain by the way you now lay out your bow but you can not equally distribute limb mass. That's if your lay-out is as you described and I'm interpreting things correctly. ART
