I'd get the .019" pins if you buy the G5. I have the ME model and like it a great deal. Very light and adjusting the sight is a breeze. The guide that comes with the sight will get you close for the pin gaps and setting if you know the speed of your arrow.

You have to decide how bright you like your pins. The factory fibers are ok. However, I replaced the factory fibers with Fitz Fibers.

I bought the sightnew off a guy here for a lot less than the stock price though.
