I just PM my opponent before the match and ask if they want to play w/ sim stats. Matt & Ovhii both wanted to do it. Much respect to Ovhij, he's more comfortable w/ 90 40 stats, but is willing to try SIM. I wish everyone else was that open.
But for all future matches, I plan on playing w/ SIM stats if my opponent is ok w/ it. Trust me all you stacked players, you'll get much more fun playing w/ SIM stats. 90 40 is going to be history soon I think.
