We used 2 speed gearboxes in 2014 and have been single speed every other year.

2014 seemed like a good year for using 2 speeds, but ironically ended up in low gear most of the year. Bottom line, the driver needs lots of practice if you end up manually shifting. Our driver was comfortable in high gear at the shop practicing one-on-none. Things got a bit more chaotic on the field three-on-three, and he didn't feel in control at top speed.

The other design consideration is acceleration and distance. Top speed might be less important than good acceleration over a short distance.
