I would recommend using #25 chain and sprockets instead, or even #35, as it is readily available at Vex and Andymark, is much more forgiving in terms of strength and precision, and comes in 1/2" hex bore sizes.
EDIT: Those are MXL pulleys, which are not commonly used due to their lower working load. GT2 or HTD pulleys are generally better for our purposes.

If we were to switch to chain on VEX, could you recommend a setup with approximately 600:1 using vex components? Using a 12t to a 60t would work for our purposes, but I don't think we can spare the 7 inches for the 60t sprocket.
Would it be ridiculous to connect 3 versaplanetary gearboxes and avoid large sprockets altogether?
Thanks for the help!
