Michael,
I stumbled upon your blog and have enjoyed reading your advice. I am currently deciding between the Gregory Baltoro 75 and 65. I have always had a 65L pack and was looking to upgrade to a new pack this year. When I compared the two packs I found that there was only four ounces difference in weight from the 65L to the 75L. So I am thinking about going to the 75 even though my gear fits in a 65L pack fine. Is there any reason not to go to the larger pack?
Thanks,
Michael
