What do you consider "light-ish"? 16oz, 12oz, 6?
I'm of the opinion that WPB shells wear out from the inside first. In this vein, I will recommend a slightly heavier 3-Layer WPB shell, as opposed to the lighter, less expensive 2 and 2.5-Layer shells - in my experience, the WPB membrane just degrades too quickly 2 and 2.5L garments. I will, however, go with 2.5L shell pants for two reasons: first is the regrettably consumable nature of pants owing to abrasion and such; and second, legs just seem to dry out more quickly than my upper body when I'm on the move.
I have an older model of the LL Bean Pathfinder jacket - with a very supple outer fabric, and I really like it as a casual or backpacking shell - fairly compact, comfortable, weight on par with my Arc Alpha shells but with a much more easy going fabric, and the very important aspect of having low-position hand pockets. Pockets on Arc Beta and Atoms insulating layers are cut high to allow unobstructed access while wearing a pack belt or harness, and as such, they are pretty miserable pocket for general loafing around. The LL Bean pockets are smartly located for the best general use.
The new Pathfinder is Gore-Tex, 3-Layer, instead of the 3-L Tek2O that Bean used for my jacket, and with that, I think the outer shell fabric isn't going to be as supple as what is on the older version - the photos make the fabric look a bit more technical, a bit more glossy, a bit more crinkly - but that type of face fabric probably holds a DWR finish better than what Bean was previously using.
