Everyone says Khopesh's are the best, but it's hard to spare the feat (plus another for otwf). So, other than Khopesh's, is it better to take piercing or slashing? I've seen puncturing weapons as rapiers and daggers, which sound really cool, and rapiers have that great crit range. On the other hand, there seems to be a bigger overall selection of slashing weapons including vorpals, eventually. There's also wounding kukri's.
I plan on being a human twf warchanter 16/3/1 bard rogue fighter if it matters.
