I use a Dive Rite zippered bellows pocket on the right side of my waist belt, mainly as something route the 7 ft. hose under on simple dives--when I'm not using a canister light. I rarely have anything inside it. SMB, light, etc., all are clipped off to D-rings. Some people route the hose under a knife or shears, but I already have my cutting device on the left side. If I recall correctly, you're using a shorter "long" hose, so you don't have this problem.
I have pocket shorts but haven't used them since acquiring a drysuit with pockets to facilitate more complex diving in my future. The pocket shorts do the job, but it's one more item of gear to don/doff, forget to bring, have to rinse, etc. If a dive doesn't call for things like a backup mask and wetnotes, I can manage fine without pockets.
