i used to comute to uni on mine. 73mm kryponite wheels worked well.
i prefer the softer flexier boards. Wider the trucks the more stable but more of a pain to turn it is.
above 40-45″ long i’d say is too long
I had a 5’6″ one for a while. Was lovely to look at but had hte turning circle of a tanker and therefore was terifying on even a gentle incline
think you might be best to try a few out to see what you like as they handle so differently given wood type, thicknesses, shapes, trucks, rubbers and wheels
unfortunatley i have no scientific way of taking that info and equating it to how it rides
