switching on affect with both the flat low current output style gold caps and
the long skinny ones that are used for solar rollers, but when I hooked my
o-scope up to it, it seemed to latch much better. The circuit work quite well
with those very efficient SMD style LEDs from solarbotics, but anything else
will barely glow. I was wanting to use this with a blue LED..that would be
cool looking, but if i cant get it to run anything over 2mA then theres no way

You bet! Use a sanding disk - it works very well in getting it pretty flat.
Then use a sheet of regular paper to give it a bit of extra polish.
