He bought those cranks, so he's clearly deaf to logic.
I suppose it depends what you want from a front shift. If you're racing and need to change fast and often, Shimano have spoiled you with their road race kit. If you just want to toss the chain onto the bailout ring a couple of times a day and don't mind how awful dragging it back up onto the main ring is when you go over the crest, then go nuts. Old people used to do both with half-step-and-granny 🙂
