Oh, wow. Thank you for all the advice.
I am afraid, it all will have to wait until the next trip, which is... still unknown and unplanned.
The climb to Laban Rata took too much out of me and I couldn't get myself to risk the attack to the summit. Just the 1st part of the climb took 8-1/2 hours. Shoosh! Should have taken more effort to train. My companions tried but still fell short of the peak. I urged them to bring the K20D and the WR. They came back with some photos. The view is great but since they were not familiar enough with the camera, I am sure I could have done much better.... if.
The climb down was another 5 hours. That was yesterday. Took the plane ride home and am just posting to say that I ache all over.
