Exactly right! It's my "mission in life" to correct all the examples of that out there and get people switched around to getting the load worked out first, /then/ buying the driver and motors. I wonder why so many people ('cause it isn't just you, trust me) go for the motors first? I guess there are a lot of people trying to sell motors and drivers who don't ask about the load... they just want to sell the motors and drivers! LOL...
