Not sure if this is the right forum, but more it if nessisary. I've been looking into getting a rolling rack case for my setup so I don't have to haul around a 55 pound power amp (QSC USA 1310) with just my arms. I'm wondering, since the power amp and all the other rack stuff is bolted to the rack, wouldn't that cause some terrible vibrations when the rack is rolling around (Like on a sidewalk, persay?). I'm looking at the Gator 6 space rolling rack because its lightweight, locks, and has wheels with one of those luggage bar handles. Maybe somebody with one of these could give me some insight.
