My roommate would always speak very highly of Neil, they liked to discuss aiming stuff and Neil was helping him learn some techniques, which I would hear about from time to time.
Sorry for your loss, thanks for letting the community know.
I was up at the Sands in Grand Rapids Mi and played Neil for about five hrs. I am a low A player and he gave me the seven and I still couldn't keep up with this guy. He was on fire. On top of it all, he is a bundle of knowledge. Great instructor.
