Welche Bänder produzieren mehr Einschliff?

Danke!!
Entscheidend dürfte dieser Satz von Phono-Max sein:

Von 528 an bestehen selbst bei höchsten Anforderungen nicht die geringsten Bedenken. Das heißt, alles, was an ernst zu nehmendem Bandmaterial diesseits des 525 vorliegt, kann rauf und runter verwendet werden, ohne mit einem Verschleiß rechnen zu müssen, der über das unvermeidliche Maß hinausginge.

Zur Erklärung, wie ich auf diese Frage komme:
In Zuge einer Diskussion über Bandmaterial für Bandechos wurden folgende Links präsentiert:

Out of the makes of tape we have tested, certain types of Ampex tape are a definite No, as the abrasive qualities found in some of these tapes can actually wear grooves in your heads, also Agfa, Sony, Fugi all shed oxides and stick to the heads. Best look for jingle tape or try Maxell - the better quality Maxell tape will give you reasonable results and 50 hours use

To resume and simplify: there are basically two types of tapes considering their behavior towards the heads: the "smooth" ones and the "rough" ones, the latter being more abrasive. A good question is: why would anyone produce a magnetic tape that is known to be harmful to the magnetic heads on the precious recording machines?
You don't have to be an analog-recording expert to guess that it was some kind of a trade-off between sparing the heads and having the best of audio quality. Remember the lubricants mentioned above? It is already mentioned that if you put too much of these you can spoil the magnetic consistency of material, and lower the audio quality.
So it is no wonder that some of the "rough" tapes were the ones giving the best audio results. Like the legendary Agfa PER 525 mastering tape, and some of the BASF LGRs MASTERING TAPES of older production. People used to call them the "sand paper" tapes (of course, it was still not that bad), and were still using them.
