Dave MacLeod has climbed a new Font 8b at his home crag, Dumbarton Rock. Perfect Crime is a 30-move roof problem adding a Font 8a+ cave traverse into Dave's existing problem, Sabotage, Font 8a+. The 2 sections are separated by a painful kneebar shake out. Dave had been trying the line throught the winter season and completed it the day before leaving for a trip to the Frankenjura. During his stay in Frankenjura Dave repeated Markus Bock's Armstrong (F8c).
