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.
