I read about this trick a couple years ago, and once, when I was away from home, I needed to replace my BDC and only had a BCC in my spares... so I tried it, and it worked perfectly. Now, I tend to buy BDC when I find them cheap, but in a pinch, I know I can use a BCC
I still have four boxes of BCC (that I bought 2 years ago), but I've not used my KPT2 tanks in many months. I'll probably pay them forward eventually, and just stick with my Aerotanks and KPT3-minis, and only buy BDC from here on? I do like the BDC better for flavor and they have a much wider range of available resistances... not to mention the last 50 I bought were only $0.77 each, which is darn cheap!
