Not having a car, on match days I have to travel with someone else and usually away changing are very compact shall we say, and this means I need a very compact bag that holds everything I need (as I sometimes keep), I find that my GN PP Duffle holds everything I need with ease, and has compartments for afterwards (deodrant, dosh, drinks, food, shoesetc etc).
Like you, I used to have a thing for everything being seperated, but fell out with this as it simply wasnt very practical for nets whe you have 2/3 minutes to pad up. The best bag at my club is the big Salix (not stand up) or the Newbery UZI apx I think, both are simply throw all your kit into the bag and offer superior room to any other bag on the market IMO. I have had the Newbery SPS bag and used the Kookaburra 1000 bag and GM Original duplex bag, all 3 have lots of space, but aren't very practical. I think you'll find that bags such as the GM Duplex dont hold the Morrant pads either, the choice is yours.
