Most modern civil rucksacks I have seen don't really offer the option to attach something over or under the rucksack.
And I expect the perfect female fit from a modern rucksack, not from a bag of the eighties.
I think you hit the nail on the head, and no we don't want a long discussion about what hammer to use when hitting the nail on the head:***::***:
Most modern rucksacks are in my opinion not designed for hiking, they are made down to a cost not quality, if you look back to the earlier rucksacks, the 80's, these were the ones that were innovative in design albeit they were quite heavy as the material used were mainly canvas,etc, but as you can still buy these are a testament to their value and longevity.
I find that most of the modern---non military style--- rucksacks are not very well designed and don't offer the options of the earlier models they tend to be too gimmicky, and lacking in separate compartments.
I myself mainly use a LK35 which I must admit was at first quite uncomfortable, but once adjusted and fettled to suit becomes quite comfortable, and coupled with the external frame is quite useful.
But again it depends on the individual, and what needs to be carried, for example how many modern rucksacks have a fitting to carry an axe, as well as straps for external things such as wood, sleeping bags, mats etc.as well as good internal dimensions.
I do agree a sticky about rucksacks would be a good thing with honest reviews,
