I caught this one on a 5 wgt
so you can use a 5 wgt for bass. Generally I use a 6 wgt for my bass fishing but I have an 8 wgt for my larger and bulkier flies, 4 and 5 inch poppers, 6 and 7 inch streamers. I wouldn't call most of the streams and lakes I fish gin clear, visibility might be 3 or 4 feet and some have a tannic stain to them. There's a lake I go to in Northern Ontario that I would call gin clear, you can see bottom in 8 to 10 feet of water. I use the same patterns there that I use around here.
If you fly fished for trout, I'm a dry fly snob. Translated to bass fishing, I fish a lot of top water patterns. I tie my own flies. I use a lot of pre-formed soft foam popper bodies and the rest are made out of craft foam sheets. So, poppers, Sneaky Pete style sliders, Gurglers, Crease Flies, Sliders, and a few with no name. Sub-surface, streamers, I don't use many woolly buggers. Baitfish patterns, Calcasieu Pig Boats,
Mop flies, crayfish and large nymph patterns, a couple that try and mimic various soft plastics.
