I have tried a few sub- seven pound rifles in my days as well, and I find that I just shoot better with a 7.5-8 pound rifle. Especially off-hand or when out of breath from running up a ridge at 10,000 feet.
Well, you and I are in the same camp, but based on comments on this forum we're also in the minority.
I guess all those military snipers with their heavy rifles are complete idiots for lugging them around when a Kimber MT or similar lightweight will do the same job.
I'm not getting rid of my lightweights, but I'm also aware of their limitations. For me, I think a good midweight (7.25 - 8lbs all-up weight - scoped w/ sling and rounds) is about ideal for an all-around hunting platform, including one for the mountains.
But I will admit I'm a bit of a pussy and like packing lighter rifles in the highcountry
And yes, count me in as one of those alternate lifestyle 270 users.
