I don't know Bryan, but it sounds to me that what you are looking for is more theory than reality. In MY humble opinion, just because one 3W is designed one way and a different one another way, doesn't necessarily mean you will actually begin to hit fairway woods well if you pick the right one. If you can't seem to hit your fairway woods all that great, I would be more concerned with WHY that might be the case. It's much more likely that it is a swing issue, or quite possibly, a mental issue. It was both in my case.
Certainly, having a club in your hands in which you have confidence will help, but what worked for me was analyzing what my fairway wood problem was and figuring out the solution. I now play a Titleist 910F wood, not considered to be a game improvement wood by any stretch of the imagination, yet I now pull it out with complete confidence, many times a round. There was a time, not all that long ago, I rarely touched my fairway wood due to complete lack of confidence. Since finding and fixing my problem, it is one of my favorite clubs to hit.
One thing I might recommend is to ditch your 3W and opt for a 4W. You will see much more consistency with little loss of distance. Certainly shop for one that feels good to you, because that will only add to the confidence. And if it means comparing specs on various woods to see which SHOULD be right for you, then go ahead and compare. Just don't necessarily pick one purely based on the specs.
BTW, my problem was over-swinging---trying to kill it---which caused too much inconsistency in returning clubface to ball squarely. After a while, I was afraid to hit my F-wood. I spent a lot of time working on this on the range with no one around to see me fail as I worked through it. Now, I take 2 easy practice swings, focusing on very little movement and keeping my right elbow in, then step up to the ball and use the same easy tempo and the ball takes off and flies straight and long nearly every time. It has really changed my game and added to my confidence on the course.
I am no authority on clubs or swings, but I have a LOT of experience with lack of confidence issues. They overran my game a few years ago. It is my bet that you will hit any brand of fairway wood much better once you figure out why you aren't, at present, making good contact. Solve that issue, then find a club that feels good, and you will hit it consistently well the majority of the time, again, IMHO. I have been there.
