The Only time I cycled my NiMH or NiCAD's was when they are new.
First charge on the provided charger for around 10C Hours (10x capacity).

Then use the battery and run it through a charge/discharge cycle in the week when its not in use.
After 3 or 4 cycles (about a month) I don't bother cycling them anylonger. I do this more for peace of mind that the battery is delivering the capacity its rated for. I had some really dud NiMH and NiCAD packs in the past and switched to LiFePO4 batteries thereafter.
