Thats my point, Slipstream gets done a lot whereas Ag Treatment and Borderline have been repeated maybe once, if ever. Same with Reality Bath, serac fall is too frequent and in fact maybe MORE active now than during the first ascent(when it occurred every 20 or 30 hours) whereas Riptide and Gimme Shelter, with less frequent serac fall, have been done a lot more.
I thought I read on LTV that due to glacial retreat one of the Fay ice bulges had vanished making a former overhanging ice pitch into WI2. In that sense it sure as hell doesn't get done anymore.
