After lengthy considerations and research I came across this tape.
It serves its purpose well. Due to its strength, it prevents nicks and notches on the edges. As was to be read in other reviews already but the strength of the tape also provides a certain recalcitrance during processing. So care must be taken when To-The-Corner-bonding, that the adhesive surface is large enough on both sides. Otherwise, the tape will be detached and "aimed at". If one (possibly two staggered layers stick) the attention it keeps very well.
