I'm pretty happy with these sizes. Proning today for the first time in a few months on a 72cm, I realized that it's just too short for waves over waist high (at my skill level at least). 80cm seems like a good upgrade, as when I tried 85cm previously it felt a hair to long. I'm not going to personally buy the 80 for some time.
For Wing, I've also got the 93 on order as well. I recently got my 100cm back in the rotation with the 925 and 725 for the first time and had a blast. Set a personal best speed and had a ton of fun dw bump riding in chest high tightly packed swell. No chance of a breach. The 93 with the stiffer build, faster, and better turning section, should be the Goldilocks! It will also open up better control of the 925+ wings.
Yeh that's it. The 72 can be too short in certain codnrions unless your a gun - and the 85 (which is all I use) whilst great to wing - is difficult to keep it high enough for power when pumping.
