As far as the formatting goes, I think most people prefer to see lines written verically not horizontally. Even among the books that do use the "horizontal" format like thegreek and sia, I think mega is the hardest on the eyes.
I think some others made some valid pints about the juice. If you are going to try to promote yourself as a low vig book for football and basket ball, you can't gouge peopel on all the other lines. If I have to choose between pinn and mega, then its true at mega I get -104 on the FULL game for football abd basket ball vs -105 at pinn. But on halftimne lines, and in every other sport there is no comparison.
So it just seems to me that Megasb is really only for people who have more than enough capiatl to fund both pinn and megasb, and just want to save themselves an extra cent in juice during football and basketball. But otherwise I can't see any other reason to deposit there. I just don't undrstand what customers they are targeting.
