Fully agree, thinking the cases of "limestone vagitis" may be playing a part in some of the advice here. There is middle ground between slamming a bike 4" and stock height, making it*more*enjoyable for him at just an inch or 2 drop. Afterall, this is a streetbike the he rides to appreciate riding in general. I say, if it inspires confidence to have better footing.....just do it. Cheap, easy, and totally reversible at any time.
