: That will be the trick this year: the ability to change to a lower gear on the fly. Kudos to you and your team, Dodd!

Andy, sorry I must have overstated. We can't shift on the fly. It's the old fashioned way, changing sprockets in the pits. With the drill gearbox (which we prefer to run in high) in series with a chain and sprocket pair, we chose two different driving sprocket sizes that give a reasonable spread of the 4 ratio steps between low-low and high-high. We just decided to make that easy to do for once. It's only 'quick change' compared to drifting and driving pins. I'm assuming we'll settle on an overall ratio during test/practise/break/fix 'week' and leave it there.
