I don't really like them breaking tradition. Leo and Raph have the cutting weapons, Mikey and Don have the bashing weapons. This created a fun distinction between the turtles. I really disliked the episodes where Donny was disappointed in his bo staff and it kept breaking. The fact that he could use what was on the surface an underwhelming weapon made Donny all the cooler. Why not give Leo and Raph some AK47s? Why not start an arms race? No, you make do with what you have. Keep the weapons the same. Eastman and Laird struck gold with their original designs. No need to tamper with them.
