The pipe cleaners should be fine - I use a fairly thin string to LST my plants, and usually get them tied pretty tight. Worst I've seen so far is some light denting on the topside of the branch from the downward pressure. I'd think that something as soft and malleable as a pipe cleaner wouldn't do much harm at all.
