I've never fished the 8142, but do own the 8139-3. It is my go-to winter rod, but since my winter steelhead fishing is limited, I also use it on rivers like the Clearwater. I fish an 8/9 WA 45 and a 630 gr compact skagit. I want to find a longer short belly like FF 55 or Vector, but just haven't taken the time to figure that our yet. It throws a dry line w/ a size 8 hair wing or length of T-14 with a dumbbell eye leach equally well.I would rate it an 8+ so I'm confident in it's ability to handle larger fish.
