Hmm, I'd have to agree with 2slow on this one. I havent been using my Triton charger very long, but it definitely says to charge Nicds at 1C for fast charge. It's right there in black and white in the manual. I also have a 1650mah 6V NiMh pack in one of my planes, and I think the manual only recommends a max charge rate of 2C for that one.
