Stiff coil wires have there own advantages. They are direct leads of the internal coils, a full-copper current path means less solder joints, less resistance, much higher melting point, making it safer @ higher amperage. As an example, Most of the very robust Neu motors have stiff wires, but letting the solder carry 100+A amperage is not an easy task, their recently made 1527s has a lot of complaint on the noodle silicone wire de-soldered and fallen out of the motor.

Castle on the other hand, did much better job in the coil - silicone wire soldering and fixing. Opening the rear endbell you can find a noticeable amount of epoxy holding the wires in place, the solder may melt, but won't fall out. Castle-Neu motors doubtlessly fit ground vehicles better, on an expense of the above advantages.
