I'm pretty sure they are the same thing. I don't have a shockflyer to look at but the ones I've seen had the same carbon spars as they sell at depronusa. I've bought some at the lhs but found the depronusa ones to be stiffer (not to metion a lot cheaper). just remember the flat spars bend very easy in one direction but are very stiff in the other, they have to be stood up on edge for a wing (either glued to the edge or in a slot) you'll figure out how to put them in once you play with them (if you haven't allready used some before). good luck.
