My local group will be starting Worldwound this Thursday. So far we have a cavalier, magus, monk, druid, and one other who is undecided. I plan on playing a knife master rogue, however this would leave the party without trapfinding. Would it be worth it to take a one or two level dip into trapper (ranger archetype) who gets trapfinding at level 1? I am slightly wary of this because I would lose sneak attack dice, which is the focus of the knife master if I took more than a one level dip. However I would gain a free two weapon fighting feat with a two level dip (along with a higher BAB and fort save and favored enemy: evil outsider).
