Ive found the windshield wipers on a lot of models to have the effect of cheapening the model or making it look odd. 3 rail models in general have an odd too about them even if you fix the pilot there are other things that give them that "off" look.
I love the LOKSound decoders and they are one of the main reasons I am going to 2 rail. The open endedness of the products really makes them versatile and user friendly. The ability to customize the outputs is fantastic.
