Had the 509 in my old 340, and have the 528 in my 360. The 509 would barely idle down to 1000 in gear, but I can idle the 528 down to 750, yet is way stronger all the way across the board. Nice stick. I'd like to duplicate the profile of my 528/1.6 rocker on a roller stick. Adding the faster action of the roller would probably get me my 10 sec time slip.
