TubberRoe: Look at the steaks - how do you think I like them??
Seriously, they're wicked. The results were better on the 44 day (somewhere around there) aged stuff I posted here last time I did them. They were a lot nuttier and, ummm buttery/funky I'd say, more of a texture change as well. Only trouble is the longer you age and the thicker the crust = the more you lose. There's no off smells or aromas to speak of coming off these. I believe that because a regular fridge is usually colder that the enzyme action is maybe a little slower than it would be at say 40 F. Most of us keep the fridge colder, like 35 F. Regardless, I liked the 44 day stuff more, it was more tender and funky. 35 days or so might be the sweet spot for me but that's a personal taste preference as it continues to change over time.
Not sure what you mean by 'whole cuts'? We used to dry age whole quarters back when I was a custom meat-cutter/butcher in the '80's

These started as whole bone-in, cap-off loin and were cut down to manageable sizes, and so I'd have epic meaty beef ribs.
I lost almost 50% by weight to trimmings on the boneless cap-off ribeye. This would be quite a bit less with a bone-in cap-on piece since they would act as a protective layer; we can't eat the bone anyway (which you'd leave on) and the fat-cap would protect the meat. There's less % waste as the hunk o meat size increases as well.
All-in-all these bags are great. They allow slower dehydration in a regular fridge that likely runs 30 or 40 % humidity, so anybody can do it at home. 'Normal' dry-aging requires 80 % or more and decent air circulation. You just place the bagged meat on a rack in the fridge for full circulation, turning it every day or so.
PS: Bring me a giant dry-aged ribeye from the market and I'll tell you

Hard to compare grassfed beef to grainfed in any format. This stuff was AAA grainfed.
