3 children - I believe the micro-adjust would still be viable and valuable. I would try to keep the adjustments very small (close to mechanical centershot).

BG/Bruce - I prefer to shoot at the top of my draw weight range - which is only 60 for me - so I hate to give up any more draw weight. I would not cut from the nock end. I would just remove the insert with a drill bit, cut from the insert end and re-glue.
