Newbie question about unicycle types

I bought a uni and can now ride it forwards, at least. However, I was thinking of using it as commuter transport (I work about 2.5km from home). Problem is, the wheels are fairly small (16"), and it´s very hard work doing any appreciable distance. Is a larger wheeled uni a more viable proposition for commuting longer distances on pavements? If so, could someone recommend a model?

Check out this thread… it covers the exact same question.

Thanks, Maestro…just the thread I should have searched for!!! Answers all my questions and points me towards a 24 or 26" uni. Maybe both. (You can never have enough unicycles…)
