Lee of Brianna can be found in major tournaments such as the US Open, the Derby...etc.
As far as I know, he has been in this business for a long time. The company is not a flashy outfit but they seem quite trustworthy to me.
When I went to the US Open to display my cues, I had some problems with my display rack (it was shipped but never arrived in the arena). Needless to say I was really upset and worried. Lee's booth was next to mine, although we did not know each other, he was kind enough to offer a helping hand, for which I am very grateful.
Lee sells cue building parts, builds his own cues, sells some cues from other makers, and does leather wrap and other repair work for his customers. I believe he has been doing that for many years.
Lee is not a flashy kind of a guy and does not really talk much.
I have never tried the shafts you mentioned so I really cannot tell you anything about them. All I can tell you is my personal experience and impression of the person.
Hope this helps,
Richard
