Pro-M Question

So i know Pro-M is no longer around, i have been looking around for a MAS and came across PMAS. wich advertises as Pro-M. Just wondering if they are the same thing, the actually sensor looks a little different and doesnt have "Pro-M" on it. Also wondering what size will suit me best.. im planning on 70mm TB, Trickflow Streeetheat and maybe a stage 1 cam from trickflow. Cars is mostly stock, with UP, CIA, and LT, O/r-H. thanx!
