lightweight but higher current cells?

Can anybody recommend a cell or cells that will handle 25-30A, but are lightweight? I have a bunch of old 1700SCRs & SCEs, but was hoping for a little better cell with today's technology. They would be powering a geared cobalt 035, in a plane that will weigh about 3 lbs. I'm looking for the best performance/weight balance; ie, I know I could go to a really lightweight cell for more performance at the expense of duration, or for a big cell (3000NiMH for instance) for duration at the expense of performance. I'm thinking maybe the CP1700, but I have absolutely zero experience with any of the modern (last 5 years) cells over 1AH.

Try a pushed pack of 4/5RC (think you know them as CP1700).

Look into Sanyo 4/5aup NiMH cells. Do a search here and on the web for opinions. These people have a datasheet you can dl.
