You are taking a lot more than I normally do, so I guess itll be ok. Howveer I normally dont do any birding. Enjyo your vacation ... I thought about teh tripod, but both of mine are heavy, and I would have had to pay $ 25 each way for them. I htink Im going to pick up a cheapie once I get to Hawiai, then leave it with my son for his PS when I go home. Im not taking any heavy lenses, so I think Ill be abel to get away with that. Paul.
