Most efficient way to access Liveapi

Hi, wondered if anyone had a feel for the most efficient way to access the live api through the liveapi object in js.

My choices are essentially between creating one object and using Goto to change the path each time I want to access/update a property or creating a new Liveapi object each time using the id of the object.

I'm guessing the latter is the way to go but wondered if none has any practical experience of this?

Thanks, L
