Using LLA to offset limbs from centerline seems like an odd path to me, you would get sideways push from string on arrow.. might end up with a very sensitive bow.
Alternatively, since I shoot lightweight limbs, I have cut into my risers another 1/8" to get past center as on all my other bows. Worked great for me. But I limit to 35# max on fingertips. Some others here have also cut in and had good luck, not sure what weights they shot.
Probably simplest to just use a different arrow spine or more tip weight. Few bows from 70's were cut past center, and they shot fine.
Well, personally I would not take a rasp file to a pretty wood riser.
Not really what I'd prefer, but the solution would be as stated to add more tip weight to weaken the arrow, or maybe fully bottom out the limb bolts to up the poundage. Changing the brace height may also possibly affect dynamic spine?
