Great advice above! My suggestion does not deal with equipment. A decision I made when my wife expressed a similar sentiment, was to make sure she enjoyed her first outing. To achieve that, I hired a guide to take her on private water where I knew she would catch some nice fish and she would not ever hear me say "You're doing it wrong." Worked brilliantly. She came back and shared things with me that I did not know and we have enjoyed fishing together ever since. You need to make sure that your wife has a good first day.

As far as equipment, a nice 7'6" rod in a 4-5 wt should serve her well. Shorter than 7 ft or longer than 8 ft would be a mistake from what you have said.

Another +1 for the NFC rods that are 7.5 4wt. They are really, really good rods for a great price. Strong, faster glass with alot of backbone. Was catching large cutthroat last summer in a CO high mountain lake and they handled the fish with ease. The extra speed to the rod makes it good for distance casting and was able to handle wind a bit better than other rods I've handled. Really good value!

Great choice on the T&T rod. Hope she likes it that series is fabulous I fished my 7’10” 5 wt. today and thoroughly enjoyed the experience.

I would reach out to Bill at W. Jude Fly Rods , he has some nice offerings of his own , along with a vast knowledge of tapers (in particular) to a variety of fishing applications , Shane Gray would also be a great source , and keep your eye out in the classifieds , maybe post a wanted ad , always top quality sticks comin up for sale here ..
