I'm 6'6", 280, with a 22" torso….so I'd actually say you're lucky as I had a very tough time finding something to fit me. I'm also broad with a 52XXL jacket. All the same names "should" fit you that you can find throughout the forums (i.e. Gossamer Gear, ULA-Equipment, Mountain Laurel Designs, Six Moon Designs, Granite Gear, etc.). Basically, most of these manufacturers would consider you in their normal to large range. Probably a good starting point would be for you to know your torso size as that's more important than your height and weight. You can't go wrong with any of these manufacturers.
Yes you'll need to say "no this" or "no that" to lighten your load, but lightweight backpackers can find a way to be very comfortable with smart gear choices, dual use items, and in the end, by simply picking lightweight options for things they really want to bring (i.e fishing gear in your case). You can bring everything you need and still be very comfortable. At 22 pounds, there are probably a lot of concessions out there which you'll need to make. Others I'm sure will take more time to address them, but start with the big three and consider this: pack – less than 2 pounds (see above), tent/tarp – less than 2.5 pounds (tarptent.com, Gossamer Gear SpinnTwinn, MLD, SMD, etc.), sleeping system – less than 1.5 pounds (Western Mountaineering, Feathered Friends, Montbell, GoLite, etc.). Again, there are a ton of options to meet this goal (quite easily actually) and my advice is to buy the pack LAST as you'll need to know what you're going to put in it. There are many ways to go light and leaving stuff you actually want at home may make you miserable. Start with the basics. Throw in a set of DriDucks for rain gear, a lightweight alcohol or esbit stove, a single cup cook system, a minimalized first aid kit, mini Swiss Army knife, some basic layering (i.e. merino wool, lightweight down, etc.), platys instead of Nalgene's, keychain LED instead of a flashlight, closed cell pad instead of inflatable mattress, chemical water treatment instead of a pump, posseum down gloves and beanie instead of heavier options, etc., you'll make it under 10 pounds fairly quickly.
Basically….read Ryan Jordan's book…"Lightweight Backing and Camping" or Ray Jardine's "Trail Life" or "Beyond Backpacking"…all I believe sold on this site (or Amazon.com).
