... I don't need the adjust-ability of the Koni Sports but I worry the Special Actives will not be a good fit.
Why not just go with the Koni Sport? As soon as they're on the car, you don't need to touch them anyways so them being adjustable doesn't really play much of a factor. What it does enable you to do is match your dampers to your springs, so if your needs change down the road and you want to move away from the linear Eibach's you've got some room to move. Also, as the shock ages and ultimately gets softer over time, you can put a few clicks of rebound back into them to run them even longer. Just think of the adjust-ability as the ability to match dampers to springs, not to run different rebound settings day to day. Set it, and forget it.
I got fed up waiting for Bilstein as well and ordered the Koni Sport Kit (usa progressive pro-kit). Another "fixed" system you can check out is the Racingline Sport Kit which apparently uses a custom valved Koni shock. User "Teemmy" got these recently for about $790. They look like a great option as well:
