In some ways, I feel like Sabian is missing an opportunity by giving you very little clue as to what the cymbal was designated as prior to its refinishing and badging.
The series (i.e. AA, AAX, HH, HHX, etc.) is somewhat easy to deduce, but the model is often not. I know Sabian's marketing is trying to push that as part of the fun of sorting through SR2s at your local shop, but obviously, the refinishing and somewhat generic classifications are to protect the sales of their main lines.
In my experience, the rough finish they apply to the SR2s make them a little more prone to breakage (especially with thin and medium crashes), and it's a bummer when you fall in love with an SR2 cymbal you were using, and you want to replace it with something similar. It took me a while, but I figured out that a 19" Thin SR2 I was completely smitten with was actually a 19" HHX Fierce Crash originally. It took me a lot of time and work to figure it out, but I'm glad I did.
Unfortunately, the real-deal HHX Fierce Crashes are over double what I paid for my SR2, but now I've been treating it with much more care, knowing that. Ha!
