I'm looking for similar advice. I used the coolie dualies last year with great success. The coolie dualies were designed after the Molded plastic wheels. Many of the teams I see using the molded plastic wheels use two of the molded plastic wheels offset so a roller is always coming in contact.

The coolie dualies replace the concept of two offset molded plastic wheel for half the weight and price.

I have not used the plastic molded wheels, so I am also interested in team's experiences with the molded plastic omnis as well as the Alum. Omni.
