You are a hard-man. 60M ropes in the Mountains?! The vast majority of routes were put up w/ 30, 40, or 50M ropes.
Answer: 50M is fine. If I were to repeat it, I'd bring a 30M and a pull-cord.
IMHO, Chopping block is the finest climb in the larger basin, except perhaps the 5.7 on Himmel? Auto? Horn.
