I'm building a Pre-A 009 and I must say if you can afford the Avitt DLC coating, go for it! I'm amazed everytime I look at it. It looks completly different than the DSN finish. Mine has a DSN dial at the moment, but I'm waiting for my dial from The Zigmeister to pop in.
I'm going to use this post to talk about how great of a guy The Zigmeister is. My original dial was stolen on the way back to me and The Zigmeister took his own personal dial that he was going to use and is going to lume that and send it my way. I can only say great things about the guy thus far! Can't wait to get it back so I can install it and finally have my perfect 009. I'll post pictures of it when it's complete. But The Zigmeister/FGD/Avitt is the way to go with a pre-a 009.
