They are not scarce enough to be worthwhile for the custom shop. Overall the general advice I see is, unless it is a circle T, it's not worth it. Using someone like BOS (especially to get the original finish and a fraction of the cost) or someone else is the better option.
Last I talked with the CPO rep, it may not be back to normal for a few more months, but their inventory is still severely limited. My recent orders were missing headcovers etc, that I used to always get as they claimed.
The biggest problem since the move is that the inventory is gutted. They used to get so many new items in everyday, most of the time. The shafts being available and clearance section etc.
If those don't return back to normal it will stay pretty lackluster.
There's still a couple swag putters on 2ndswing for $115 and $138 mint condition for those interested.
They are solid putters like anything else, it all ends up being aesthetics and feel for whatever you want to use. You just need to be confident and happy with what you have more than anything.
