I definitely go for the more simpler looking cues. I prefer the more natural looking cues, the ones without the extra bling, colour's decals. Predator BK series is a prime example. I like how they break, but I do not like how they are a walking advertisement.
Things I like :
-Full splice wrapless.
-simple ringwork
-if there is a wrap, I like simple ringwork above and below. i prefer the look because it has a deliberate start and end of the wrap, and doesn't looking it was carved into the cue.
- if it is a wrap, soft tanned leather, not repurposed, or printed, or glossed.
things i usually do not like (on occasion, something just works, and i like it, even if it is not something that would normally appeal to me):
- floating points
- points in the butt
- a lot of bling
- decals
- rounded points
- overly bright contrasting veneers. (white/black is ok, if it is to make the points obvious into the forearm)
- repurposed, glossy or textured wraps.
- blue ferrules - this is more a pet peeve for my equipment. i don't really care about other peoples. I like to keep mine clean.
All that said, my main player is a Cohen and flashier than i normally would be drawn to. ebony, with copper inlays and curly maple recuts (i think they are recuts). so i break a lot of my standards for my main player
I find it the right mix, and elegant, rather than gaudy.
Not really a peeve about equipment, but i hate to see someone with nice equipment decide to play hockey with the shaft. i don't know why so many will use their shaft to move redirect balls that are moving. I see guys with high end predator cues, smashing the side of the shaft into balls. Also, i cant stand when someone smashes the butt of the cue into the floor, or uses their cue like a walking stick.
