I've always "softened" those sharp edges. It's OK that I don't pay to have it done. More time and effort? Yep. Worth it? Maybe. I just do it.

Back on topic...I'm glad to see this block, and the Ritter SB stuff, finally looking like the issues have been resolved and decent parts finally available for reasonable money and time waiting.

If the results don't match the theory, change the theory.
