I don’t know if it would distract me while shooting. But the look would nag at me. Like seeing the cue when I’m switching from my break cue to playing cue or when putting it together. The look would bother me enough that I don’t think I’d ever like the shaft. Could I get past that if the shaft played great? Probably not because I doubt it would play orders of magnitude better than other options. So I’d likely never get to where I really liked it.
Some is almost a subconscious nag. For instance, I don’t like shafts that don’t match the ringwork on the butt. It is common now for players to use a performance shaft with just a black collar or whatever that doesn’t match the butt. You don’t notice that when shooting but it bothers me to the point I don’t like it. Could I tolerate a backup shaft having a plain collar? Maybe, probably, but it would be a true backup. Like I said it is subjective. If the cue had a plain black collar, no problem. Likewise, I could tolerate a variety of shafts and cues with different looks, but if the look is something I really dislike or it nags me like the mismatch shaft rings, I don’t want it. The half and half shaft seems to fit in that category for me. But I haven’t seen one in person or hit with one.
