late to this party.
the Alaskan guide bag is nice!! quiet, very protective. in winter, when you are wearing a jacket, it is the best. you dont even need to secure it closed. your glass wont fall out. but in summer, i found the fabric too close to the back of my neck. it wore on me.
i ordered the FHF. took forever to get it. order it in the summer, trust me. Paul is a badass. nice as hell. a real craftsman. the FHF protects my glass less. there are gaps in the side that let in dust. sometimes when bored in the field, i will pull out a brush and clean the glass. no biggie. the small pockets are less usable. i put in a squeeze toy varmint call (came with my Alaskan guide bag) into one and i now have a impromptu varmint call at my finger tips. it sounds awesome. the other pocket is small and almost useless. whatever.
the straps on the FHF are tight. i am not a fattie, but with multiple layers of clothing, i could see it as a problem. if you are not built/shaped like a hungry long distance runner, talk to paul about your dimensions. he has a more conservative set of straps. my old straps fit, but the new ones have tag ends free just incase i slip into a heavy coat.
hope this helps someone.
