I put a lot of time into getting some more made up a few years ago. Pace Produts did phase1s, they were grey, these were the bomb, they weren't interested in doing some more.)
So, I got in contact with the guys who did the Phase 2s, which are black. At the time I was in contact with Darran at G-Werks who told me about them (they had G60 ones done). He said they needed to be hard anodized or they would wear. The guys who made them said the opposite, said they needed to be soft anodized but use a harder alloy or they would wear. (the hard alloy wouldn't take hard anodizing)
So thats where I got stuck, I didn't know which way to go. I wasn't interested in working to get a shoddy product that would wear out together.
What we need is to make some with an alloy body, then steel teeth, they would be a lot lighter than full steel, but they would be a "lifetime" product unlike alloy ones.
