I ride the TMS and have demoed the PEs.  I found that the trouble makers are lighter.  Both skis do groomed runs the same.  The TMs have a wider tail, so i found they can pull you out of bad landing easier than the PEs.  The PEs felt more solid, but the TM has held up for me so far.  I found the TM to be a much better park ski since is it light and good for crap landings and carves the pipe well.  The skis perform equally on groomed and moguls and such so i got the TMs.  I live i nthe eats, so i can't comment on the pow' skiing.
