Myself and a few others did try LiFe at around the same time. The pack came from GM / Graupner, and it was very similar in feel to 5 cell mod. Probably a touch more kick at the start of the run (as the voltage was a touch higher) but more drop off as the discharge curve wasn't as flat.

However, by that time, LiPo was fully established, and despite a couple of manufactures being keen to go down the LiFe route, it didn't happen. I thought it might happen if there were a lot of serious safety issues with LiPo. There have been a few for sure, but not as many as I thought there might have been.
