I prefer the bigger knobs too, I have lots of 2hp modular gear and the little micro knobs are OK to a point.....!
There is a Robin Vincent Youtube vid about the 104, he loves it....

Then the previous vid about the 103 from Divkid sold it to me anyway!

Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
