I picked a great time to start my own version of this one. My doomswitch is stuck on MASSIVE BRUTALITY
I played 10 normal and 10 turbo and had just an nasty run. Cashed in 1 out of 10 Turbo's and cashed in 6 of the 10 normals. Only 3 wins, which might not be too bad considering. The harshest part was that in all 3 of my 2nd places, all of my opponents basically said "Oh cool. 2nd place. Profit." And proceeded to crack some monsters with some "interesting" hands, to say the least.
Overall down only about $1.50 but the beats I took in those turbos were pretty nasty. Needless to say, I'm done with the turbos. 10 normals at a time I think will be a decent enough volume.
