Resurrecting an old thread, but......Brock, that is an AWESOME chart! /ubbthreads/images/graemlins/bowdown.gif
I was wondering whether I should even bother with NiMH for my KL1, until I saw your chart and I am impressed indeed. I'm planning to use 2 x 2/3AF GP 1100mAH high rate cells, in a "high rate" KL1 (modded to 500mA). I won't get that kind of runtime you posted, but it should be more than enough for my needs.
