Mike - I own and used a 2 1/2" No-hole, a 2 1/2" standard, and a 4" standard yoke. I used them all, along with a longeron yoke that I borrowed for just a couple of rivets. I found it useful to know who else around you is building, and what yokes they had - sort of a "yoke coop". Don't buy a specialty yoke that someone else already has!
