With respect to all the great players in the past, My vote would be Sky. I've just witnessed too many times when he hits that switch in different games.
I was at JOB's during the midnight madness tournament the night he ran 3-10 packs. He was mad because he never ran a 11 in the race to 11 format.
I was also at the bank ring game race to 100 rails in the action room at DCC when towards the end he ran 25 in BTR banks to pretty much close it out on the other players. That's most likely the highest BTR run ever in an action match. Ray should really post that video clip up for public viewing.
On a bar table, he has the highest gear and is also, hands down the best bar table player in the world right now and maybe ever.
Same in Banks, except for maybe Billy and JB in his prime.
One pocket probably Scott, running 18 and out three times in one session for the huge cash against Dippy is something that will probably never be repeated. I also credit his high gear and aggressive style play into changing the game of one pocket into the more offensive style game as we know it today.
