Wow, thank you for all of the replies and information! It's a lot to go through. My magnets and pole pieces have arrived, so I'm going to play around with them for a little bit. I do have a feeling I won't be happy with it no matter what I do, but we'll see!
I listened to the SD metal pickup comparison video over and over and I really like the sound of the Alterative 8! I will report back with my final decision.
