Actually the effect is the same. However, I'll suggest changing the preq's. Instead of base attack of "+8", make it base attack of "max damage of weapon." Since you only choose 1 weapon, a dagger could be chosen with a base attack of +4, a short sword with a +6 or a greataxe with a +12. This with more power to the smaller weapon (which i think is good) and gives rogues n' knife fighter types an edge. The only problem (that i can see) would be with unarmed, which would stay at +8 (maybe). What do you guys think?
