You make a valid point...especially since I'm currently wearing a Sub Date
It'll be interesting to see how it shakes out. I think the competitive aspect helps make the cue things a little different....nobody is using a mechanical watch to time races for example...no matter how many Rolex sponsorship signs you may see there. But there is an equal amount of emotional connection to cues as there is to watches I'd say (for people who are into both obviously).
I'll add that for me, I'd much rather play with my custom cues and wood shafts for fun and messing around. But when it comes to serious play, league or tournament play, where making or missing a single ball will have an impact, that is where I'm happy to have my carbon low deflection shafts, extensions, etc. With watches, nothing in my life relies on being accurate to the second or even minute. If my watch is a minute fast or slow my life will go on as normal with absolutely zero impact.
