i understand..i know how going through the proper channels works,but i am glad you are doing it.i think it can only help.
p90...as a long time floyd user(15 years),i can tell you that to this day i don't like the rout involved,the way the edges wear out and affect tuning,cutting off the ball ends,the complicated intonation setting procedure,constantly flipping the guitar to adjust the spring tension,then tune it,then adjust,then tune...
the great thing about the kahler is that all of the adjustments are done from the top,with the strings on....
