I'd say that the key here is - work out what you carry at a typical gameday, and then build your load carrying gear around that. The OP mentioned a battle belt, so yes a solution that works around it - they've already hinted that some of the larger, bulkier carriers will get in the way of this.
I started off with just a belt rig, then went to a plate carrier. As a predominantly midcap user, I found that it was easy to overload and then wouldn't be comfortable, as well as stopping me from going prone. I think over the course of about 18 months I switched between, belt, belt + vest, vest + no belt, webbing, SADF chest rig + belt, PLCE assault vest, Arktis chest rig, and now finally I'm on a Platatac Peacekeeper chest rig.
You're unlikely to find a load carrying solution to suit every event, or one that works really well for someone else and works for you likewise. If you've got mates with different gear then ask if you can see what their kit is like, or if you don't mind a bit of trial and error then maybe go for a chest rig as people have suggested and see if it works - if not then try and return or sell it on (or hoard it like I do).
