Just my preference but I own 4 eight weights and 2 6 weights. Not to mention my 4 and 5 wt trout rods.I gave my 7 weight away to a newbie friend. The 8 and 6 will get it done for everything in Everglades national park including tarpon up to 40 lbs,I don’t fish for the adults. I’ve fished Everglades for 50 years and an 8 and a 6 does it all for me. My personal preference, others may prefer a 9 and a 7. Try a few friends outfits and see what you like best.I guess the issue I'm having currently, being limited to just one rod, and it being a 9wt, is that it just feels too heavy for a good deal of applications I use it for. Fish in pretty clear conditions a lot and the 9wt just feels like it can spooks fish too much with how big the line is in the clear water. Also, not providing enough finesse in some more close quarters situations, like back in the mangroves. Doesn't quite feel like the generalist rod weight that I was initially getting it for when I first started fly fishing a couple years back, and as I get better with casting, it just feels like too much rod. Hence why I'm considering stepping down to an 8 weight for bigger fish and a 6 weight for smaller fish or when I need a little more finesse and fine placing of flies for the spooky, clear water fish.
