Nothing that hasn't already been said, but I use a condor battle belt with an H harness.
It fits really well under my ghillie tog and allows me to lie down comfortably and attach a hydration carrier on the back which is really nice on those really hot days in a ghillie.
It may not work as well for you if your using a full 2 piece ghillie though.
Ultimately the only person using your kit is you, so if your happy with it that's all that's needed. try a few different configurations and find one you like. You may even want different set ups for different game sizes, as I wouldn't say you need a drag bag if your just skirmishing. But to each their own.
One thing thats for sure is if your serious about learning how to play right, you should attend a sniper clinic as soon as it's available.
