SVB's grandpa: you done good, it's true it can shark and irritate the other guy if you slowplay an obvious out. I find shane's pretty entertaining to watch. No antics but great shooting.
I don't find corey boring because every so often he plays a shot in a way that needs a crazy stroke, and he pulls it off, and it's beautiful to see. He also likes caroms and sometimes comes up with pretty creative shots.
I get excited seeing if efren and earl, and weirdly also thorsten. He is very serious at the table and there's nothing but pure mechanics in the way he shoots, but I love to watch him plow through racks and you can sometimes see how smart he is in the decisions he makes, the routes he puts the cue ball on, etc. It's fun to watch him solve problems in both straight pool and 9b.
Kid D. also bores me. The stuff he does is annoying and kinda funny at first, but after you've seen it a while you're just impatient for something to finally happen... a shot, a miscue, a nervous breakdown, something. I kinda see that impatience as a form of boredom. I also like watching js, he does let his emotion show a little, but never to the point of being low class or sharking the other player.
