Loop Midge probably is not the lightest reel, but it probably is the lightest "big arbor" reel you can get. about 3.45" Dia. This is one of my go-to reel. no drag, great fun to fish with. my another large arbor 3 weight light reel. Lamson purist 2. about 3.5" dia. a little bit heavier than Loop, but still feel amazing light in hand. a fun reel too.
