I'm also worried about lifting those 9 pound tetras. Last year it was difficult to lift our 3 pound max hook with the van door motor (however, we had no reduction just a directly connected motor). Team 980 had a beautiful arm last year for lifting that large cap ball if you got a chance to see it. We want to design something similar to that. Where does everyone plan to get the muscle for that kind of lifting?

You'll have to use a sick reduction if you're planning on lifting a lot tetras (3-4?). A lot of this game has to do with physics also, you simply do not want 10 pounds hanging 2-3 feet out while moving around.
