I'm obviously the least macho, poorest shooting guy on this thread which is why I like a lightweight on a backpack hunt, and get as close to make the kill as possible. Gumping up a svelte rifle with a Bubba Hubble isn't my idea of how to make a lightweight rifle more packable/shootable.
On the flats I'll always take more barrel/forward weight. I don't really care how heavy a rig for that applications is, within reason of course. And of course, the same rig is perfectly at home in the mountains, I just don't happen to want to carry it there. Again, at my age, I'm not especially keen on backpacking a heavy rifle, being particularly feminine and un-manly, what with my vagina and all.
But we only have ourselves to please...
