I have used several of the less costly foam tapes: SRAM, MSW, Salsa and Cinelli. Overall I prefer using Cinelli and that’s what I’m running now.
I use touring bars with grips and need about half a roll per side to tape the bar forward of the grips to the center.
Cinelli seems to be a bit thicker and seems just right for me, but watch out for overlap and the strong adhesive: put the adhesive on the bar, not the tape. Salsa tape handles well and is easy to rewrap but Cinelli feels better on my bars.
