Thanks Random Orbits and nitsujwalker
That's pretty much what I was thinking.
The max weight allowance is 25 kilos - but that is for the porter and while hiking
Me? well, it's up to me and how much the air carrier let me carry as a personal bag item.
- not to mention how much I really want to carry on my back everyday.
Here in the PNW, I usually carry anything from 15-25 pounds in a day hike, accounting for a FF and one or two lenses. As a rule, I fill-in my water bladder - 3 liters, which come to 7-8 pounds alone.
The backpack is about 2-3 pounds, and then depends in the season and location to hike - more clothing, food or other gear like crampons, - aside the 10 plus essentails.
In Nepal, I will carry less water, and will bring a water filter (which I always carry in the summer anyway),
A bunch of essentials can be carried in the duffel bag, except for hiking food, rainjacket and extra layer
Tempted to bring the TS-E 24, but indeed te 14, 35 and 80-200 is a good range.
Almost makes me wish I bought the TSE17mm instead of the 14mm.....trades anyone

Yes, no flash, but I have a lightweight gitzo tripod to bring ( less than 2 pounds with head)
The 40D goes along the idea of carrying the TSE - however it does require different batteries, and is in the process of becoming a full-time IR (full-spectrum) camera. Tempting too to shoot in IR there, but I think I rather bring the LX-3, for candid shots/rainy days
With the 35, I can share the CPL and a ND with the 80-200 - unless I bring a ring converter...and all the sudden it's becoming a lot of gear ...LOL
My other concern is recharging the batteries. Tea-houses where we will lodge overnight, will have outlets, but one has to pay for using them, and fight the competion (well, sort of)
Thniking of a solar charger. Solar panel charging battery pack, that then will recharge camera batteries type
So any imput or experiences with these sort of packs would be very helpfull too.
Thanks once again.
