Hi Jay,
Check out the Jigging Master GT Compact Belt.... defintely comfy to wear all day and forget about it... nice and small, but just the right size...
Other similar options would be the FISHERMAN Flat harness, and HOTS lite...
some of the others like the Seven Seas and MC Works belts are amazing, but you need to be the exact right size for them I've found... the curve of the plate itself is a bit limiting if you not the exact size to fit the curve...
Personally I prefer a flatter more versatile plate...
