What brand / thickness of electric fencing tape?

[RunRunReindeer]

Currently using a mixture of tape & rope but looking to replace as it's all getting a bit worn out; wondering if anyone would recommend a particular brand, and whether 12.5 / 20 / 40 mm wide is best? Thanks.
Anyone tried Robinsons Requisite Cross Tape? It's cheap, but maybe a false economy??

40mm is more visible, but useless as a temporary (plastic stacks) fence line. Works great on wooden posts.

Rope seems to catch the wind less and gets less tangled if you move it regularly (but is more expensive and heavier).
