Forget NiMH, Forget Lipos, Forget Li-Ion.... I use The New improved Sub C Alkaline Cells. J/K

I love lipos, like many others said, the weight is awesome, but I still keep my IB4200s, I like bashing around with them alot. NiMH seems to take more abuse physical abuse than Lipos, but Lipos can perform a hell of a lot better. But make sure you buy good Lipos, I've used a bunch of cheap crapy ones, and they expand alot. Even though I didn't exceed the recommended Discharge rates. I like NiMH, but love Lipos.
