because of the additional weight, 48 spokes take around 10% more energy to be accellerated just as fast as a comparable 36h wheelset...
This is an important point, because in polo there is a lot of stop-start, so improved acceleration is a good reason to think about ways of making your wheels lighter. Remember it's rotating weight that is most important in acceleration, not the overall weight of the bike.
The biggest downside of 26" wheels (IMO) is the paucity of suitable tyres, when compared with 700c.
