dude, i just now looked at those shots. those are great! looks like someone has a nice DSLR paired with a circular polarizer.
do you have, or have you tried, 4s a123's? esp. concerning the 'volt up to eliminate the problem' comment. i'm curious, as i plan to run 4s2p a123s in mine. i was worried it might be too much, but i also planned to gear down a lot.
