Two top British Heavyweights of the late 80s and early 90s. If there was any Heavyweight out there that was slower than Bruno, it was Mason. Bruno also had better skills, longer harder jab and more power. "However" Mason had the better chin and overall toughness...and although not quite as powerful as Bruno..he punched pretty damned hard himself. This is what would have happened: Bruno would be winning every second of every round until the 9 or 10th round when Mason would catch him with a huge hook (of some sort) and finish him off shortly thereafter. Mason by late TKO.
It surely would have been fun while it lasted but I think Bruno would have busted Mason up so that he had never seen the 9th round
