The Black Tape situation is different than the White Textured Tape. I preferred the thin, brittle Columbia 300 black tape over the AMF tape, which was softer and had a slightly more tacky feel to it. The C300 tape, being very thin, allowed very minor adjustments.
Now that C300 is not making this tape, the remaining choices are very different.
The Ebonite tape is softer and kind of tacky like the AMF tape.
The new Brunswick tape has the same feel as the old C300 tape, but it's a LOT thicker, providing more coarse adjustments.
Anyone have a stash of the C300 tape (normally sold in the blue boxes) in 3/4" size that they want to part with?
