If I am going to grind, I'd rather a cash table but I don't think I have it in me to go as long as some of you guys or like some of the pro's. If I'm feeling on, I play 3 houra-ish max with more than a 15 min break in between 3 hour sessions. I like to stay sharp.
I also prefer to play online as soon as I wake up in the morning online. I am a morning person I should add haha. I would imagine most poker people are night owls.
