I will say this at the risk of sounding like I’m arguing with myself. You can’t be so fastidious about equipment that you collapse mentally if conditions aren’t right. I had that come up in a 3C tournament where my opponent, through his own fault, had to borrow a cue for our match. I won’t go into all the details, but he did not handle the situation well at all. I liked my chances against him at that point. Ironically I used a cue I bought from him to win.

. Some players get so worked up about balls, cloth etc… they hurt their chances when competing.
I bet that if you took Hu’s perfect 1911 away and sent him to the OK Corral with an off the shelf pistol he’d focus more on the gunfight than the fact the ergonomics or sights etc… were different. That doesn’t mean ignoring equipment, it means that competitors pay attention to their equipment AND compete with what they have that moment.
