Iota is the 9th and smallest of the 20-character, Greek alphabet. That's what wikis tell me.
There will always be a massive distinction between old and new equipment. There is at the highest levels of golfin skill, as well as the middle and bottom shelves. The Romantic poets among us (and I fall headlong into that klatch from time to time) will persevere in their efforts to recycle the old as equal to the new.
