I used to stay at Pettecote Junction Campground so I used to fish it just below the mouth of Cedar Run maybe two or three times and a mile or so down the road once when I was staying at a different place.
It's big water which I really don't care for because I like to move around and explore new holes and IF there other folks fishing in a stretch (and there are over Memorial Day Weekend) you are kind of stuck fishing in the same spot unless you want to get in your car and move someplace else.
The fish I caught were all stockers with the exception of a smallmouth I caught one morning at the stretch further down the road. Ironically that was the last time I fished Pine for trout.
However, if you fished in Ansonia you should have driven 20 miles up the road to the Class A part of Pine which is worth fishing if only because it gets really small and you can walk across it anywhere you want.
