Is There a 'Perfect Extension?'

I read this article:
http://www.T-Nation.com/article/bodybuilding/exercise_of_the_week_gironda_perfect_curl

I wondered if there’s an equivalent to that for triceps. As far as I could think of, you could do the reverse of those instructions with cable tricep extensions and end-up with the “Gironda Perfect Extension”. Am I correct and is this a good idea for an exercise?

palms up or down

palms down

Sounds good, I’ve been sliding pipe through TRX handles at waist height, keep my body planked at about 40degrees, and do BW skull crushers to my forehead, pivoting on my toes, kills my long head, and my abs. These will be worth a shot as soon as I get out of my garage and into a gym though. thanks
