how about a 70-200/2.8 with a 2x tele converter?
if weight is at such a premium...then maybe consider getting the canon s5 or something with 20x optical zoom. shiokness. can take movie somemore.
but if i were to go on safari, maybe a 100-400 with a 2x TC, or a bigma 50-500 with TC.
edit: oh yah, and a magnum.44 in my girlfriend's handbag
