I chose the 5+4, because I like to stay out on the field as long as possible. Also, it gives you the option on the amount of pods you want to carry. The "Base 5" are positioned along your back, while the other 4 are collaspible. This allows you to use 1, 2, 3, or even all 4 of the other pod carrires/holders. I found this pack a valuable resource when I went to Skirmish (Invasion of Normandy Scenario Game). I was able to use all 9 pods, and a hopper (190 balls), on one tank (Crossfire 88/4500). Also, I will sometimes place a bottle of water in the collapsible pod holders, as a means of hydration-on-the-go. All you need to do to wash it,..... place it inside of a pillow case, and put it in the washing machine!!!!!
If you are a serious scenario player, or a hard-core "Shoot-A-Holic", this is the pack for you. Pick your color, get the belt (and pods), and then have a blast!!!!! It gets an 8 out of 10..... because the belt cost extra.
