This was all the gear and food I used on this hike.
The things I would change start with the 40 degree sleeping bag. I have exchanged it for a Golite ultra 20, because I was very cold at night. I usually sleep very warm , but after the long days of hiking into the night I needed a warmer bag than normal. I think good sleep is very important and it sure makes the trip more fun.
My converted xc skating poles (4 oz) worked great, but I have removed the Leki metal tips and glued on Leki rubber tips. I think these will work much better on rock slabs, won't stick in soft soil, be quieter, and give some cushion.
My gaiters were from REI, but I only used them one day. The dirt was not that bad without them and I would not take any on my next trip. I would rather bring more socks.
I used a Katadyn filtering water bottle and it worked great. It is nice to be able to refill it with water without even taking off my pack, and carrying less water lowered my pack weight.
My shoes were Salomon xa pro 3d with a Sole insole. My feet were very comfortable with no pain on the soles at all. Toed socks stopped any blisters from forming.
My food was Hammer Perpetuem and Recoverite, which work great and was very light, but I would add more variety next time. A couple of gels and power bars each day would be good. Another item that worked was Hammer Endurolytes. These are electrolytes replacement caps and are a must have in hot weather.
Otherwise all I would do is trim an ounce or two from some of the other gear.
Another gear issue is a bear container. I did not take one. I talked about it with the permit issuing ranger in Lone Pine, and we worked out a plan of using bear storage lockers till outside the container required area. I stayed at the Tuolumne Meadows Hiker Camp for the one night in Yosemite NP. After calling 911 to report a small wildfire at Trinity Lakes I pasted the ranger responding to the call. She asked me about my bear container and I told her I was hiking all the way to Tuolumne Meadows. I don't think she believed me, but let me kept hiking any way. I was hoping to use a Ursa bag, but it seems they lost their approval last year.
And yet another issue was the WAG Bag in the Whitney Zone. Again, I did not have one, and I ended up running fast for the boundary past Crabtree. There seems to be some confusion between the different government agencies. The NP ranger at Crabtree (I talked to her on my family backpack trip) said that I would not need one (I don't think she wanted hikers to drop them off at her station in a used condition). The USFS ranger did want me to use one and then carry it to Yosemite (not going to happen). This is a small glitch in an otherwise very successful program.
