Simply put I do not use temporary bar tape even though I tend to use really inexpensive stuff ($2.70 US shipped to my door)...
But before I tape, I build the bike and ride it for a while before applying the bar tape. This allows me to fine tune where the levers will finally be located, what stem will feel the most comfortable and even what bar to use...
Once satisfied, I tape away and usually find the end result to be comfortable, well done and looking good....
