There are lots of thread regarding what lenses to take to Alaska but couldn't find thread on what camera bags to take on day excursions.
Here's what I've decided to take.
5D, 16-35, 24-70(still debating), 100-400, 1.4X(pins taped to work with 100-400), CPL, G9(indoor snaps), 220EX, Monopod, Tripod (for Photo Safari), 80GIG worth of CFs, Nexto PSD, Kata Raincoat, My raincoat, 40D(for 100-400 but still debating)
I don't want to take the bag off in less than ideal weather to change lenses during the excursion. So tradition backpack type is out, sling type bag isn't anymore comfortable than shoulder bags with shoulder harness for walking. So sling type of bags are out including Fastpacks ( I need to take it off to access lenses)
Of the bags in my collection:
1. Primus - good for 3 lens setup + 100-400 in upper compartment. Room for my raincoat. I can access camera while walking. I can change lenses without putting down the bag. Cons: heavy and big
2. Domke F-2 with TT Shoulder harness - easy to access camera or lenses. Comfortable when worn as backpack. Cons: no room for monopod or tripod, no room for raincoat, too heavy when worn as shoulder bag
3. Flipside 300 - compact size, fairly easy access to lenses without putting the bag down, light weight bag. Cons: no room for raincoat
4. TT Changeup with lens changer- Small size, can be worn as lumbar bag or waist pack for easy access to lenses or camera. Cons: no way to put body with 100-400 mounted inside the bag (big minus as I think 100-400 will be most used lens), limited to 3 lenses, no room for monopod or tipod
Being a bag-a-holic, I will spring for an another bag if needed 
I appreciate your thoughts and comments.

Se thinks I carry way too much camera "stuff".
