AV or HP pinion gear?

hey guys, im wondering what the difference between HP and AV pinion gears are, i am getting 50354 RC AV Pinion Set 16/17T for my TA03F which i am restoring and i am going to run a LRP 17x2 motor with the stock black gears, but am wondering if a HP pinoin gear would be worth getting. cheers.

A pinion is a pinion... the difference between AV and HP might be pitch, I don't know off the top of my head. The best pinion you can get is a titanium one in my opinion. They are super lightweight and look trick, plus some are actually smaller but with the same number of teeth which allows you to run larger pinions.
