Anyone running NiMH cells over LiPo? -

I'm still playing with my recent MGT conversion, scrapping together a few more bucks for good cells, and am wondering if anyone is using NiMH cells by choice. If so, was it due to cost savings over LiPo? No noticeable performance gains for your application?
I've been toying with old, and junky, NiMH cell packs, ranging from 8 cells, to 12 cells, and then to 2 8 cells in series with my connector, giving me 16 cells to play with at one test session.
I've settled on 4s Lipo for my voltage range, which is a smidge more than 12 cells. 12 cells isn't much to carry around for a MGT, or a Neu 1515 1/y with a Quark 125B, but in the game of electricity and RC, lighter is better.
But, at what cost? I can get almost 3 12 cell packs by shopping around for the same price as one 4s2p LiPo pack, so I'm stuck in the middle. Runtime will be increased by the LiPo pack, and weight halved, so bonus there, but again, the cost....
Just bouncing around ideas in my head, and now the board. Oh yeah, what's the max range temp for the Quark 125? I had it warm to the touch, but will bust out the temp gun to tune in my voltage next time I'm out.
Thanks,
