In reply to Hugh Cottam:
According to Adrian Berry, Steve McClure did use pre-placed gear on The Big Issue.
That would make Hirayama's lead the first clean one. Impressive stuff.
". Several years ago Steve McClure and myself made the second and third ascents of the Pembroke route The Big Issue. This route was given huge publicity, and used to push an anti-bolt pro-environmental agenda.
But I can tell you that viewed close-up, after the bolts were hammered flat, and alternative fixed protection (jammed wires and a peg) were placed, it was a total mess. The route has never really been climbed in a traditional style to this day, and remains a de-facto sport route - just that now it’s even more of an eyesore. After our ascents, we removed as much of the jammed gear as we could - but is a jammed wire really “better” than a stainless bolt?"
