With the original trophy taker, if you shoot cock vane up do the other two vanes pass on the outside of the launcher arm? In other words, is it easy to get fletching clearance? I'm having a fit with my NAP quiktune 2000 and blazers...thought I had it fixed but its still a problem.

I've shot both ways, cock vane up or down. Some bows work better one way or the other. But to answer your q, cock vane up will work fine.

I usually start in the cock vane up position and then turn the cock vane towards the riser until the bottom right vane is lined up with the widest point between the launcher and the riser.
