Late answer to your question, but yes - Schwalbe Pro Ones were crap for me. Loads of punctures (average of one per 100km), didn't seal, cut up really badly, didn't handle as well as standard schwalbe ones. (Note: Bear in mind I use my one bike for London commute, club runs and everything.)
IRC formula x-guard - 3500km on a rear (I'm 17 stone) before broken bottle slashed to the thread (didn't puncture but didn't fancy keeping it after), no punctures, better grip, roll better too. Front still going strong.
Is anyone else a fan of IRC here, apart from the sole UK importer (and a road.cc review I read)? Think I'l go for those but I dunno.
