There is a a stuck no.6 nut low down on bloody Sunday (was already there before we started climbing ). I had a proper go at getting it out while on second but to no avail. There is still useable space in the placement but given it's location the nut is going to rust insitu in no time. If anyone fancies doing a public service next time you climb it, bring a hammer for your second. Reckon a few taps with it on a nutkey should get it out.
