Hi Danny,
I also fly a Savannah and my local airfield has all circuits to the west, so depending on the wind direction I may fly either a left or right hand circuit. So, as IBob says, just stick with it and you will not be fussed by right hand circuits. Personally I find it an advantage as it means I am happy with either, so landing at a different airfield with a RH circuit is no drama. In fact I have found many airfields in Victoria seem to have RH circuits either for noise abatement or terrain avoidance, so it's definitely an advantage to have such experience.
Cheers,
Neil
