Battery Types and their Limitations. Questions?

Because of my job, my rc plane hobby was put on hold for about 5 years. Now, I found that I am able to rejuvinate my Ni-Cd batteries but the nickel metal hydride batteries seemed beyond repair. I invested quite a bit in these Ni-H batteries and now they appear useless.What is your experience with these batteries? How do the new LiPO batteries hold up during long periods of inactivity?

I've switched most of my RC flight-packs over to LiFePO4 chemistry now and love it. I can charge at the field in just a few minutes and the extra voltage headroom provided by these batteries gives me more speed/ torque from my servos while ensuring there are no "reboot" issues with

2.4GHz receivers.

What's more, there's very little difference in price. In fact my sport models (.40-.90 sized) now use a pack of two 1350mAH LiFePO4 cells from DealExtreme which cost me less than US$10 to make, including the wiring and heatshrink.
