Why do you want to have a gear powertrain? Saying that 341 and 25 have them is not a sufficient answer. What advantages does it you? What issues with other powertrain solutions you've used does it solve?

Not to mention it will save on hex bearings, which are notoriously hard to procure for FRC teams. Based on the picture, it cuts a minimum of 18 hex bearings out of the design, and presumably 36 if you were to use round bearings in their place on the idler gears. Using Vex prices, that would also result in over $120 in savings, as well.
