Just a quick update on my experience with iron adapters.
For starters I was able to contact both Club Conex and All Fit.  Both started by going directly to their website.  For Club Conex I had to simply do an inquiry thru the site and I got a response via email with a quote for what I wanted.  Then I’d get a link to actually complete the order.  After waiting for the link I decided to visit AllFit.com.  Was able to make my order directly on the website, and that is the connector I decided to get.  It just looked cleaner.  That said, All Fit iron connectors are a little more expensive.  You’ll need a drill press to bore out the hosel and they do offer a drill bit that worked well. All my forged heads worked like a charm.  The STI2 was a little more difficult but worked.  BUT the KE4 Max was a much more challenging task, so just a heads up if anyone is wanting to use the all fit adapter in that head.
All said, very satisfied with the adapters and the process.
Hope this helps anyone who is interested in pursuing this process.

did you ever get the link from CC to complete the order?

Unfortunately not. I could have reached back to the rep who contacted me but didn’t since I had decided on all-fit connectors.
If you want that contact I’ll post it. He was courteous but had been out of the office last week.

that would be great Shof. Can’t really afford to shift manufacturers at this point.

The Fuze-Fit adapters were $17.50 each for hosel and shaft.
