You could compare yours with the gear lists on the home page of this forum (in the left-hand column--there's a 7-day list and a 3-day list). That will give you an idea of whether you've left out something important. I hope you're weighing this stuff! I have everything listed on a spreadsheet, with weights. While this was a big help in getting my pack weight down, its main purpose now is as a checklist which I print out before every trip.

Is the "rainfly" part of your tent or a separate tarp? If it's part of your tent, just include it with the tent. If it's a separate tarp, do you really need it?
