Well after more than ten visits to Sunnyside, one of my long standing projects has finally come to an end.
"One of a kind" was put up by Chris Webb Parsons in 2010 and has held the grade of V13 after three repeats!
Probably not one of best problems I've ever tried. However it did pose quite a large significance for me being the first of the grade and after 40 + hours of sieging I feel a great burden has been lifted.
Anyway, Mark has made a great video of the accent... Enjoy!
