the Handle is essentially a grab loop to assist in putting on the pack on. it is not a luggage carry. you do have the option of padding it yourself.
this is how i\'ve been carrying mine and the pretty much stay in place
i can see to an extent your personal issue with the dividers. but its a give and take. where the dividers in the others bags you mentioned except the Kata are limited as to positioning due to the lack of hook and loop on all surfaces the ICU allows for any point and a little more stitching points may stabilize the fabric itself
on the Kata product. it is laminated to itself and to a point a reasonable idea. you can get a kit to customize the dividers but in execution its not all that much fun to play with when you have to position and reposition.
i do like the thin dividers on TT product but i\'ll take the overall freeform capability of the fstop.
as to slippage out of the slots. not hapenning with my stuff. maybe you just need more padding or snugging up. i\'ve removed dividers for mine and set them up to be quite cosy in their little beds. i don\'t even use the cross straps. sliding out with my back pushing against the load?
all of them are less then perfect in one way or another.
