Looks great/have not used

Was going to use on my current project which had an innovators west balancer on it. I did not realize that innovators west basically makes you Swiss cheese your crank shaft to pin. The ati balancer would have just taken away more material and I wasn’t a big fan since the whole point of cog is no slip and it will find a weak point (crank snout). I decided against using after I realized and instead went with a turbo. I will be using on another project with a good fresh crank. Quality is outstanding and it looks insane. Can’t wait to see/hear it in action.
