What are the negative things you've heard re the Uni Loc pin?
I know some have had the stainless pin and the brass insert lock up on occasion but beyond that, no problems. Thats pretty much a rarity.
Not my favorite pin in the world but we have and had Pred cues around the house for years and never experienced a problem.
If you don't like the pin but like the cue, have the pin changed out. I wouldn't worry overly about it.
A break cue, a very small percentage of time used. You break and set it down until your next break.
