Re: correct reel and rod wt for reds need help pls!
8wt is hard to beat for many applications. However don't be caught undergunned if the wind is up or the water clarity requires larger bulky flies. Wind down here on Texas and Louisiana make below a 8wt with most flies pretty tough much of the time.
Often bushy heavy Clouser of 3/0 are used and then an 8 feels too light. We saw some bruisers that would have been tough to land in weeds with light stuff.
When wade fishing I use an 8 as Ill be doing plenty of blind casting. But from a boat a 7 & 10wt would be darn near ideal. 10wt be awfully handy if some Jacks (jack crevalle) are spotted, with these guys a 10 makes for fair reasonable length fight. Not often but these guys are around enough to make you glad you had the 10.
Won't suggest a specific rod/brand as many work (plus it just spins into a "mines better" argument) however too fast can be a hindrance for short fast accurate cast so often needed.
