It's not an easy answer for me. I had a 300/802 a couple of weeks ago, and what stuck with me was the 300. It was one of those rare nights where I felt locked in and every shot that game was legitimate, so it felt great. I didn't know I had thrown a 800 until someone mentioned it to me after we finished everything up.
There was nothing like getting that first 800 several years ago, but after you've accumulated several of each, at least for me, a good 300 is special.
