I have a 100+ year old F.E. Thomas Special (bamboo) I use for that kind of fishing. š
For that reason I would recommend a longer rod, 8'6" to 9 foot and something slower to absorb shock meaning in most cases, current Winston graphite might not fit the bill. Older Winston graphite (IM6, WT's) can be more moderate but stuff can be hard to find.
Fiberglass may be the ideal option that could provide that kind of action. There is some older Winston glass built on brown Fisher blanks out there but again, it's hard to find and pricey when found.
However if you think you an 8'0" glass rod would be OK for your needs, seek out a green Winston Stalker 8'0" 3pc 4wt fiberglass rod which is circa 2000 and slow as molasses or the 8'0" 4wt 3pc Winston Retro (brown blank) which is nowhere as slow but slower than most 8'0" Winston graphite sticks. The Retros were discontinued around 2006. The "green Stalker" was discontinued a few years prior so eBay or someone on a message board is your only option for either.
I don't know many folks who liked the green Stalker because it is so slow and they couldn't deal with the action for their type of fishing. However IMHO, it would make a great wet fly rod and you might find one more easily because they were so disliked.
For the record, even though I am a huge fan of the Winston DL4, I don't think the longer offerings are ideal for this type of fishing and even though I own the 8'0" 3wt DL4, probably the slowest graphite rod I ever cast, I wouldn't use a 3wt for swinging multiple wets.
Good luck!!
