I think that you certainly need to go fitted first. Then you will know if you need WSD. Testing would be great. I undesratnd that finding a short that has everything that you need is impossible. I would use every resource that I have. Good fitter is the first one. They usually have different bikes. I think that my coach/fitter probably has 15-20 bikes at home. He is crazy. Check with your friends and definitely shop around.
