150lbs each is pretty generous. Some outfitters have deals, like if you order the food and drinks ahead of time they fly it in free.
You get made fun of If you have to much stuff. Worst I dealt with was 700lbs of just food and snacks. Another example was 24 cases of beer for 6 days.
Worst thing I saw--- was the camp change day was poor weather. We told the guys we would make a trip but might have to turn around so they should take there sleeping bags, toiletries and medication and some food on their person, incase the second plane (with the rest of their gear) couldn't make it in. They bravely decide they only needed their fishing tackle and left in the beaver and got into the camp. The 180 with their food, sleeping bags, meds, change of clothes didn't get there till the second day. It was early season, cold, wet and windy.
Also flying in cases of water or the blue jugs is your biggest waste of useful weight! Get a water treatment system/processor. Some good ones around 100$ will filter 2L of water per minute.
IMO a big tackle box isn't necessary either, ask your outfitter what they are using to catch fish, he will probably only suggest a few colours of jigs and a couple plugs or spoons.
I took a quick look at the list and looks like way to much stuff to me. Your outfitter should look after some of those things relating to the cabin and boats and motors. I would ask if there is a coffee pot and utensils etc, axe....
And remember if the fridge and freezer are propane (probably are) if you pack it full in hot weather, it will not function as expected.
Can I ask which outfit and which lake?
