the road bridge seems to to have a regular looking bridge that will swivel and the telescope feature..seems well constructed....
i dont see the need for a telescoped length for a bridge icbw
i have never had a problem using a house cue to use the just a bridge
the justa bridge will fit around a ball and it may be taller (4.5 inches)
also you have more flexibility with regards to where on the cue ball you can hit due to its adjustable height
lastly the material in the grooves prevents any change in the feel of your shaft as happens sometimes with plastic bridges
to answer your question
yes i have one i carry in my case
and its $55 LESS than the road bridge
here is one site that sells them
