I'm going to pass down my current Pinnacle to my son. I like everything about the pack except its weight (I've trimmed it down to 28+ oz) and it struggles to carry over 25 lbs unless I augment the suspension somehow (though I suspect most frameless packs are this way). I do the latter a fair amount from either carrying items for my youngest son or lots of food for longer solo trips. Of course, the weight only lasts the first couple days. I carry a Neoair and usually a thin foam pad that really doesn't provide much support even folded 6 thicknesses.
So I'm looking for a Pinnacle replacement that weighs less. It must be at least 50 L but compress down well for smaller volumes, torso size 20-21", decent size hipbelt pockets, side pockets for bottles, and be able to carry up to 25 pounds in relative comfort. Money is also a concern so I'll have to be lucky enough to find a used one unless I MYOG. These seem like the potential options:
Gossamer Gear G4 (perhaps MYOG?)
Gossamer Gear Mariposa Plus
Granite Gear Virga
ULA Ohm (not sure belt pockets are big enough)
Which ones should I eliminate?
