I've heard 254 transitioned from BBD to surgical recently though, so take my experience with a grain of salt.

We only used surgical tubing in 2014, as it gripped the ball better than the urethane and was way cheaper and came in thinner wall thicknesses. There is no rule for how much larger we go on tubing vs the shaft/driven tube size. We have not used the urethane directly on a non-hollow shaft since 2013. In 2014 we used thin wall aluminum tube with the surgical tubing over it. This year we made some custom wheels with large OD aluminum hubs and huge urethane tubing parted to the widths we wanted. Worked well.
