Thanks for the advice. The outfitter and I actually decided to move the hunt to mid-September for better odds at the moose tag I'm adding on. Seeing as how you're going back in roughly the same time frame, how will your gear list differ?
I'm not sure I'd really change much. I brought a few extra layers of clothes that were left at camp where we flew in, but didn't use since it was so hot. I felt like I had things dialed in pretty well.
My buddy Jayson (White Mamba) above ran the Grayl water bottle filter. I had a Nalgene and a Katadyn filter. His was much faster and convenient, I'm picking one up for the next trip, I'll leave the Katadyn home and bring the Grayl and an extra Nalgene.
Light weight gloves were nice to help save our hands from the rocks and the mosquitoes.
Having two shirts was nice, we'd often get back to camp late. It was nice to have a dry shirt to put on before turning in, I'd hang the wet/sweaty one out to dry.
I'll probably also bring gaiters, we hiked through a bit of greenery and if it was wet it would have soaked my pants. We had pretty dry/warm weather. You could always run your rain pants instead, but I think having gaiters and a lighter weight paint is nice. Rain pants might be too hot, it really depends on the weather.
All of the stuff I've acquired over the last 5-7 years, I didn't go out and really buy anything prior to this trip except the helinox chair. Unless money grows on trees for you it looks like you have similar stuff already, I'm sure you'll be fine.
