i like a lighter action tip for flounder. One of the best flounder fisherman I have fished with Loosedrags has some nice set ups I would drop him an email on that question. Buck tailing and dead sticking is his specialties i learned alot from him and i bought my self a shimano reel with a light action rod and caught alot more then i did with my old set up. Good luck with the rod hunt.
I have a Penn 965 matched up to a Chaos 12-25, and I just love it! It is a pricey rod, but well worth the money. The rod has an extremely sensitve feel for Fluke, but I also use it for Stripers. Caught a 40" Striper on it this summer and it was a blast. Go to chaosrods.com. They are also at the AC Boat shows.
I have the 975. It sits in the drawer. For some reason the drag slips. Lost a king salmon in Alaska with this reel. Took it to Penn to have it serviced and it is still the same. I love Penn reels but not this one.
