In my reluctant experience, casters don't. At least they don't 
in the direction I want to go at any given time. Having fought 
the random directionality of casters way too many times, I'd 
not take exception to inline wheels. Seems to me that casters 
on one end of the dolly and inline wheels on the other might 
be the best of the positive, and the least of the negative. 
You could steer (!!!) without lifting (!!!).
