So I'm wondering if anyone has any first hand experience on the Grand Jorasses, specifically the mixed routes on the north face (Colton/Mac, Croz Spur, The Shroud, etc). What is the best time of year to do these? I've ascents recorded in almost every month of the year. What's the best time of year to hit good, technical mixed routes in the range? I'm a complete Alps neophyte!
