Frank......Mine has the "BK" dual cams.
They're "just a bit"<img src=icon_smile_wink.gif border=0 align=middle> quicker than the original Post Feed or Infinity cam.
In reality mine is probably about 20-25fps faster than a 2001 single cam version.....16 would be about right for the single cam comparison if you took the highest rated bare string single Vs. my dual with a string loop. Mine would probably do just about 340fps with a bare string....
