What is that darker spot in the middle of the rub-mark? Possibly a place where it's worn so paper thin that it is bending and near-through?
Yup. Upon much closer inspection, it appears that the darker spot in the middle is literally paper thin and looking closer at a more head on angle, a tiny hole that goes clear through the tube can be seen. I think I have an answer. This frame isn't worth building up. Back to searching for my 27" ST!
Thanks for the thoughts and guidance in this.
