I have played lots of them heads up and its pretty much all the same, you watch rack watch some more and rack again.
I played Bartrum once and I was down 8-0 before I saw the edge of a ball, all I did for 8 games was rack and kick a couple times.
I have only played Ja 3 times, the last time we played he was playing PERFECT pool, I won one game in 45-50 minutes that we played, the only win for me was from a 1-9 combo on his only dry break, Again I never shot that day. He ran 5 and out on me and missed a ball and pulled up. He played (I wont say who the next day and hit him with a 3 and then a 6 pack to win 9-2) the day after he wasnt playing like that and got beat, I have never seen him play better than those 2 days in 25 years, so yeah it was cool to actually play against something like that. I doubt I'll ever play against that again from anyone. I mite have shot 4 times in 45-50 minutes, never a open ball, except the 1-9 i won a game with and that was a tough shot by any standard.
To the OP with weight I'd like to play Efren, he offered me the 6, God I wish I played good enuff to play him with the 6, yeah he is my pick to play.
I have tried to play SVB to many times but we cant seem to match up, he respects me and I fear him so we cant ever agree on a game. He and I are friends too but I would play him for $1000/set, nothing more. I doubt we ever play.
Oh yeah one last story, I played JB banks, now there is a dandy of a game, If I made a ball i felt like i won. I did actually get to 3 once playing him. and I could tell he wasnt trying.
Its amazing how far out of reach these guys are, yet i can beat other people as bad as the champions beat me, thats something I have a hard time wraping my brain around.
erfen is who I want to play, but I need more than the 6. LOl
