First, there was the Cincinnati decks. People thought they were the bomb. The reality is that their sheet-fed press sucked - hence the big deal a while ago about getting printed on the web press.
Then, there was the transition - the move to Erlanger and the shakedown phase of that operation. There was some confusion, some complaints about quality, all justified. The early Erlanger decks were a step down from the Cincinnati decks. They were largely made in 2009 and 2010.
Then, the shakedown phase ended - Erlanger decks reached a point where they're now superior to the Cincinnati decks in terms of quality.
But, the final stage came - late last year, Erlanger was having finish issues with the Bicycle stock. I think it was 325gsm back then, but whatever it was, it's now 300gsm. The stock's a bit thinner than it used to be, still of great quality. Thinner stocks, though, won't hold up as well for crimping and other stunts.
The Bicycle deck of today isn't a bad deck at all, but Bicycle was never the top of the line for USPC. Tally Ho is now made on Aristocrat stock, a bit firmer than most Aristocrat decks. Next firmer is the Bee standard, then the Bee Casino stock is the firmest - almost too firm for some.
