i think you're right about spotting traps not affecting your m/t aptitude. i was basing my comments on the fact that there are two kinds of traps - mechanical and magic. after you get (i think) expert in spot traps, you can spot both kinds; until then only mechanical. since there is a m/t bias involved in spotting traps, i figured that if you had a high magic app it might hurt your chances of spotting one.
of course, i could be horribly wrong as well...
