Love the FDI 2i.  Went to install a heavier weight to see how it’d change my launch trajectory and found that the threads and weight that came with the head had some rust on it.

Easy to brush off but trying to think of how it got in there, best guess is something related to change in temps and condensation?  Don’t think there’s any other way for moisture to get in, no cracks that I can see.
