Bigbulls you have a point, but in the overall rating system I give a point to each blade a head has, and most of the time that evens the playing field. there are a few heads that slip through the cracks, I will admit, I am the first to admit the "system" is no where near perfect. I am considering looking into revising the scoring over this winter, but I need to play around with some ideas first, and see what if any heads change and so on. Your question is one that has come up before, along with bleeder blade sizes.
