I had a Fenwick as well Don’t recall the model but it was a pretty decent rod. I had a, I think loomiglass, that I really liked. But I snapped it setting the hook on a pontoon. Had it for a long time. That one pissed me off
Before my buddy started building custom walleye rods built off Bushido and Rainshadow Immortal blanks, I used a variety of Okuma Dead Eye spinning rods. the Dead Eye Custom DCS-S-681MXF would fit your parameters and can be found for $100 if you shop around. Otherwise take a look at some of the higher end scheels rods as well.
Ebisu Pro Spinning rod from Scheels is great and durable $125 at the moment on a discount, Elliot rods are the new leader regarding sensitivity but they will shatter if not cared for & are very pricey.
Have been using St. Croix and broke the tip on my favorite Eyecon 63MLXF and of course they don't make an exact replacement as the handle is a bit longer but close enough. I was very impressed with a Daiwa Tatula spinning reel I bought so decided to try their Tatula spinning rod. This has turned out to be a very light, sensitive outfit with plenty of backbone. The Tatula rods are close to the price of the Eyecons which is in the $150 range.
I have really enjoyed my Trika rods since they came out. They have some noteworthy engineering in their rods that definitely increases sensitivity & casting distance. I’m slowly replacing all of my “old” technology rods with Trikas. They are pretty expensive… but walleye fishing is a pretty expensive habit.
St croix has been on a downswing for while. I no longer use their products.
For an extra fast rod, Daiwa is my go to now. The RG is a walleye rod. Best $100 rod out there. I use them for finesses jigs, neds, tubes, blade baiting, and trout.
You might want to look at these I dont own one I just bought a trika on sale for $200 before I heard about them Talon xmb carbon , regular price is $300 they are on sale right now for $100
Check out Dobyns fishing rods. They have a strong following in the south among bass fishermen. They are good quality rods for the money. I have a couple of their Sierra Series Spinning rods that are very good rods. These run about $180.00, but they make less expensive models also.
