Not all of "them" do.....
I'm a 5, and I know that I don't wanna try and hang with the 7's and 8's in a regular 9-ball format. In a games won scenario, I'd get smoked, far more than an 8-ball match with the same player.
JustaDub - I read my comment and I didnt mean it to be condescending. I was a 5 in 09 and move up in Feb of this year. Of course I quietly thought I could hang with anyone but I prefer to speak softly and carry a big stick. Your attitude about playing is perfect. Play in those tourneys with your goal being to never be an easy out. Dont give up when you are down, especially when you are getting weight. I have two 5s on my team that if they would stick around and practice afte hours I could have to a 6 or 7 by next session.
