Should be common sense, but it isn't. Who wouldn't want to be playing the RIGHT club that you use EVERY hole? Everyone right? Nope. Driver fitting? Of course (and you maybe use it 10-13x a round), irons, yep. But never the putter.
Funny you'll see a ton of high and mid cappers playing Scottys and the low cappers playing whatever works best. I like the method alot, don't like the price tag. If I see one end up in the used bin I'll grab it up.
