I prefer the dividers, whether 14 or even down to 10. I once owned a nice Ogio carry bag that featured two large openings in the middle for your Driver, Fairway, and Hybrids, plus 3 dividers on each side for irons, 2 large for wedges and a putter well. That was my favorite bag for organization.
in my opinion, cart bags should have full length dividers. Especially pushcart bags. With the clubs sitting sideways, it is easier to get them in and out. I have a nice Sun Mountain bag, with a bottom that fits their push cart to avoid the bag moving around, that is set up well.
divders also help if you have lager grips.
