Again I point out that the bore, after seconds of play, is coated with condensation which then presents a new surface to the bore.
I put a barrel with a rough bore onto an upper joint with glossy bore, then played it and pulled off the MP. Looking down the bore, the condensation looks the same on both surfaces. Therefore, I'm not concerned with bore texture.
Your observations may vary. So much is subjective ... like when I clean and polish the outside of my flute, it ALWAYS sounds better. Really? (I don't think so.) But I believe it, therefore it is.
