Thanks for the post, few points I noted (Self-notes)
1) Karl's production has gone up tremendously in that particular video with Joe Rogan. It goes without saying that Joe Rogan had some touches/help or comments on the audio quality of the video, which made the video 10 times better than what Karl used to record before in his series of "Whats in the bag".
2) Joe Rogan knows his stuff, equipment-wise. I saw him talk about sharp points, curved points, and that tells me that he really is balls-deep into cues, which is fun to watch.
3) He probably owns a $300k+ worth of cues, I wonder if he doesn't sell them (Because he doesn't have to) then where will these cues end up 50-70 yrs from now.
