Well, it should be easy to see which tip you have as the part number is stamped on the bottom of the left tip.
I doubt most people would even notice the difference between the blasted or polished tips. If you are observant (and maybe OCD
) enough to tell the difference between two of the polished tips, especially from a picture, you are truly skilled.
I will admit that I did take some metal polish to the polished tips when I put them on, but mostly to get rid of the road grime, and when I went to all the trouble to put in the PSE I wanted it to look like new.
I do like that 550 edition tip.
