I also can't see how TM can benefit from making non conforming clubs. Not sure what type of market is there for it. I mean, if they create a driver that can hit 30 yds longer because of a hot face, then yes, but we all know that's not going to happen. The advantage is marginal at best. You can only make the faces so thin before it caves in. And even now, TM isn't known for having the most durable products out there.
500cc, even 600cc did exist for a time right before they imposed the 460cc limit. And even during then, not too many people were interested. It just got so big where it actually became harder to swing it and yes, to a point where aerodynamics came into play. It was no longer confidence inspiring thinking on how to swing a stick with a balloon on the end.
So really not sure why TM would even suggest such an idea cause they know very well there is a high chance it flopping. Like one of the posters said, sounds more like an ego thing.
