The advice to start building your own coils is valid. PT2 stock coils are hit and miss at best. I still have a few, so they go into a tank and I vape them until I am unhappy with them, which is usually very quickly. 8 wraps of 30ga kanthal A-1 on a 16ga needle micro coil stuffed with cotton. Takes 5 minutes once you get it down, and it costs pennies to build. You can get a 100' spool of 30ga kanthal on Amazon for about 7 bucks, shipped. Organic cotton balls, 2 bucks at RiteAid. 16ga needles, 2 bucks at Tractor Supply for 6 of them. If you don't have a torch, use a lighter.
Other than that, the aero bases are really good, with one caveat; they are not a magical device to just adjust the draw of the PT to your liking. They affect how the PT wicks juice, so too tight a draw can lead to flooding and gurgling. With a proper micro coil wicked properly with cotton and an aero base set correctly, the PT2 is a killer clearo.
