The only difference with the two bridges is the height of the feet. I personally do not think it needs a neck reset, but everyone may have their own view on it. There is plenty of string angle over the bridge, it plays great, and the bridge doesn't move around like my 1990s Starfire III bridge did when I bend strings. I also believe the bridge pickup could be lowered a bit if one was to sand the plastic cover a bit, but I didn't want to mess around with it. It plays and sounds great with D'Addario Chromes 11-50 flatwounds with pretty low action. I should probably take some more pictures with the newer bridge on it (it's set up with the newer one at the moment). Thanks for the interest everyone! There might be a deal in process.
Edit: The original pictures at the top of the thread have the newer bridge installed.
