That would be a great choice as well. I have never played the 14" Dark Crisps before, but they do sound nice. If I were going to get myself some Signature hats, those would be my choice as well. I'm not sure, but being that the dark crisp has an extra heavy bottom, I would assume the dark crisps might have a little more volume than the 2002 mediums.
My biggest worry with both of these hats is how they will blend with my other cymbals, knowing that neither of them are B20. All of my other cymbals are B20, and I've never really used a mixture of B20 and B8/whatever the sigs are made of, so I'm not really sure how they will sound together. What other cymbals are you using, and how well do you think these hi hats will mix?
