I use Novak Millenium and Millenium Pro Chargers for all of my batteries. For stubborn NiMH packs, set it on NiCd at .5A and set the threshhold (cutoff) to 13mV/cell. You will not overcharge them, just watch the temp. Once they get fairly warm, pull 'em. I have been charging batts with these chargers and using this method for years and it works fine.
Another thing you can do if you do not want to watch you batts for temp is get them started like I mentioned to where they are taking a solid charge, then switch them over to NiMH. I personally do all of my small cells on NiCd and bump up the cutoff without issue. Not sure why you would want to lower the cutoff voltage. That will make it false peak even easier.
