Hi Scott,
Welcome to the forum, I would agree with Mikey AA Fields are a very good, consistant pellet and due to that probably one of the most popular. I am currenty using Accupell, they seem to suit my Daystate a treat.
I would always recommend trying different pellets. It provides you with an appreciation of a good and bad pellet and gives you an idea what difference a bad pellet can do....
