I'm pretty sure these are above average, as I wouldn't class myself as a frequent string breaker. In a dense 18 x 20 such as the Prestige, I very rarely pop a string before cutting out.
I think I'm about to move on though... much as I like this racquet, I've lost my two biggest strengths - serve and 1hbh.
I'm at anywhere from 2-8 hours depending on the multi. Full Klip Legend was 11 or 12 hours. I can't see how having a harder poly cross in would extend the gut mains for me. OK, so the strings slide more but I think one of the reasons the Exo is such a string breaker is because the strings move so much.
