My experiences from stock class. I'm always charging at 6,5 amps to get the most punch.
1700: Takes a lot of abuse. Plenty of punch for the first minute or so, then they flat out. The higher the charge rate, the more steap the discharge rate is.
2400: Much more consistent performance. Can take some abuse, but might false peak if too much abuse.
Snayo 3000 HV's: Even more consistent than 2400. Becomes better and better for each run (havent tried more than 3 on a night though...). Abuse? I think they'll take more than people say, but I'm not sure.
An equalizer improves performance. Personally, I'm using an active one with 0,6 volts cut off. This prevents a lot of false peaks. You'll probably be amazed about your practice packs, if you tray them.
I think you should get 2-3 practise runs on every pack, to see what suit your best.
In your planning, I think it'll be best to use the NiMh's every second run, to get as many runs as possible out of them. Fill up in between with other packs, to ensure proper cooling. At least 30 minutes, preferable 2 hours. Also, save the best batteries for the mains.
