I removed the inner devides and to be honest it hasn't been that bad. The central part is nearly as spacious as an issue NI sack. The side pouches are a bit small though and only have poppers to hold the lid shut so small things tend to fall out if you are throwing the bag around.
Personally I use one but will get a new daysack, purly because I want/need to attach jetpacks to the side.
The one thing I like about the Dutch bag is that its DPM (sort of) but looks different, in a twisted (wish you are alley) kind of way...but as previously mentioned, I am sure everyone else thinks I look like a knob!
