Ah great. Realistically I think keeping the bag off the back of my legs is the main goal, so going bigger probably better than smaller too. Don’t want to squish the bag like you say either!
Yeah good point, but I think both of them would give you ample leg space. The squish also isn't that much of an issue really, unless the bag is completely filled/unsquishable and then it feels like it puts quite a bit of extra stress into the whole system.
