Earlier I did a search for "PSB" and 18 pages of results came up. I read each entry from the 18 pages that had the word "PSB" in it. Here is a recap of the important factors I found (in my opinion):

1) PSB = easy clean up, no fuzzy hair being pulled out from underneath the base.
2) PSB = can be attached with Got2BeGlued ...again, easy clean up (because the hair doesn't touch the adhesive used, no residue in hair)

These 2 things are pretty much the majority of people's consensus. However, people had a mixed opinion on the hairline, which is what I'm really interested in. In trying to find answers regarding hairline, I think I'm more confused now than before the search.

BA posted this picture of his hairline (it's a PSB front)
To me, this looks amazing. Absolutely clean and amazing.

So if PSB fronts look like this, then why are there people saying PSB will have "hairline issues"? I know about other complaints such as: PSB being hot, makes crunchy noises, is touch-detectable along edges, etc. These things are fine to me. Again, I've narrowed my curiosity to just the hairline. Please enlighten me.
And please don't make guesses (sorry if this sounds harsh). It's just that I'm interested in those who have experience with PSB hairlines. Close up pictures would be super.

Thanks everyone!
