It almost looks like a 50/50 split but if you were to divide the decisions between those using regular vises and rotary vises I think the decisions would be better defined.
Using a rotary vise paying material off a spool or card is quite convenient. With a regular vise however you must maintain tension while wrapping and most vital you must constantly
control mylar tinsel to lay it on without twisting. I'd feel very clumsy here with a card or spool in my hand.
