I'm pretty sure he is not joking and I'm more than sure its been tested in the snooker world

I can see using the bridge a lot more in snooker, necessity being the mother of all invention it just makes sense that if everyone played on a 10-12 foot table they would not use a 58 inch cue or they would have to get savvy with the bridge. Snooker has very few big breakthrough's so there isnt really a need for anything new. Ill never be good enough to know, but when the best players in the world are using something similar it seems like its more than a gimmick.
