Choice is upto you,
All I am saying is there is alot of negative press on the PAR gearsets, and I mean ALOT.
That's what you would have found if you searched through the PAR threads like the guys above suggested.
Since you haven't listed a budget and adding to this that your goal is to run 9's all day (an expensive undertaking)
PPG is an option, OS Giken etc etc the list goes on.
Personally if I was doing what you want to do.
