Hahaha. I felt the same way when I jumped on a mechanical bike after riding Di2 for a year and a half. The price premium pays for itself because it's maintenance free. I would rather pay and be maintenance free than have to fiddle with changing cables and readjusting. I will never go back to mechanical.

As far as the split here in LA... If say it's probably 70-30 mechanical wins it. But it depends what group of people you are riding with there are a ton of expensive bikes/builds out here. If you ride with a more serious group electronic will probably win it.
