The Benotto tape would get really slippery when racing in the humid month of July. There were times in early 1980's crits when my gloved hands had a death-grip on the bars so I wouldn't slip off the ends. I was very happy to switch to cork tape when it became available.
The Benotto tape, when braided, did offer more of a grip. As I recall, Bicycling Magazine had instructions for "weaving" two contrasting colors of Benotto tape together for a braided look on the bars. Does anybody still have a copy of those instruction diagrams?
