I've been lurking here for a while but this is my first post. I'm also an avid outdoorsman, and as a matter of fact I used to have my own bushcraft and wilderness skills school until the economy went into the toilet and I had to close down.
Are you also packing your overnight gear along with your photography gear? The reason I ask is that you may be able to cut some weight there depending on your needs.
A carbon fiber tripod would be the best strength to weight ratio. (I'm assuming since I don't have the budget for something like that LOL)
