Two great examples of efficient use of a 2-speed shifter this year are 968/254 (custom) and 330 (AM).

Both had a low speed around 5-6 fps and a high of 15-16 fps.

It may seem unnecessary, but I have a great perspective on these drive trains as I have played defense on 330 in about 5-6 matches (including 3 in finals) and in their shop on their practice bot. I also played defense on 968/254 in at least 4 matches.

Their low speed gave didn't allow me to out push them, and their high meant that they could easily break away. All of these teams used this advantage very well.

For reference, we had a single speed at 10 fps with a small CIM, big CIM and FP that was traction limited.



I would recommend the AndyMark.biz shifters for getting started. They take all the work out of it, and even 254/968 are planning on using the guts of them next year. My team is currently doing a prototype of the previously mentioned base with them integrated.

Overall, shifters can be very useful if you have the weight. You will never get a group to agree on this though, as it is a hot issue.
