I was going to ask for clarification on what you mean by favorite *builder*. If we are talking about the person that builds the cue, my favorite is Andy Gilbert. Extremely nice friendly guy, really listens to what you want, and does what you ask, while making whatever suggestions he thinks you might like based on what you tell him. My experience having a custom cue built to my exact specifications was an extreme pleasure in all regards, and the price was unbeatable.
Now if we are talking about how the cue plays? Well that's a whole different story. That story also goes like this: Andy Gilbert!!! His cues have a fantastic hit, look beautiful, top rate workmanship, and command respect.
All around Andy is one of those rare ones that combines excellent customer service with a pleasant personal demeanor while delivering a cue of the highest quality and playability.
I think I've made my point haha.
