i for one, did not like the BWL, was very disappointing to say the least
my buddy bought one at the same time
i sold mine pretty quick, his, we tweaked the surface multiple times until it came to life
I believe the issue for me, was that the cover was a bit to slick, way to much over under
if i would have tried a lower grit under some polish, it may have been better.
more than likely that i just match up better with mostly symmetric pieces
i cant say i have ever been in love with a piece that has higher diff numbers
im sure its just me, my .02 worth though.
so, give the piece 500 or 1000 + polish and see what it does, should be a decent amount of backend depending on what shot you have. its not really a heavy oiler
