Leatham wrote me back and said he'll take the RDS thing as a challenge. He's going to use his USPSA .45 ACP double-stack and go for completion of the CoF with only one hole no bigger than a half-dollar.
But seriously, as an afterthought, I think the RDS option could seriously help encourage some seniors and possibly some folks with conditions like mild Parkinson's or MS. If you're used to the red dot, managing/timing the wobble can be much more accurate to handle than with irons.
