Hey Full Flat Grind. Based on your pic, it seems like you already have experience with breaking in a DLC model. If the new one feels THAT different, go ahead and send it back under warranty. Spyderco will make it right and you won't have to keep worrying about it.
I got an all-black PM2 a couple weeks back and on the first open, it made me forget any other folders I'd been considering. It was like butter. Two weeks later, it's like cream. I can whisper it to open. So if you've already spent two or three evenings cycling it without being happy, I think you've done your diligence.
