Lehner 1950/6 vs 1950/6 high amp

I haven't owned any Lehners, but it's my understanding that you do gain some efficiency by going with the hi-amp version of the motor. The difference, however, is negligible. I believe that the really big deal is that the hi amp version comes with wire leads sticking out of the motor rather than those puny 3mm plugs. That way, you can use more appropriate connectors or direct solder your motor for a better connection.
