I am glad I went the NiZn route as it was easy and cheap. I even bought an extra pack of batteries just in case. It is nice when I flip it on and see 6.6 volts after a night of racing. I can easily go two weeks of racing, no problem, and never be below 6 volts. I recharge at 6.2 to 6.3 volts. I noticed that all glitching goes away past 6 volts.
