You know how easy it would be to compare a companies FF offering to their traditional front side progressive blank with a table of values showing which powers would benefit the most from the FF in their line of products. I think drk even mentioned that one manufacturer had a color coded chart in thier literature, too bad we can't quantify the difference beyond red, yellow, green, and blue. Make no mistake the manufacturers are pretty much correct inthe fact that most would not understand how to utilize these figures so they use what we learned in elementary school LCD or Least Common Denominator. That means all of us get to be treated like the dumbest of us.
