Hey man, welcome to GH
Firstly, I spend a lot of time up in Manchester, mainly in Longsight (shudder) but yeah, it's mostly a nice place.
I would reccommend the WASD. I have just got one, and the build quality is good, however the caps aren't great, and I'm already thinking of getting a thicker set of caps for it. All of your options you have listed are pretty good, although I haven't heard a lot about the Pure Pro. The Duckys mostly have backlights so that may put you off, it may not, but my firend loves his TKL Ducky. And I have only heard good things about Filcos.
If you are looking at switches, I loooooooove the feel of clears, but if you are typing a lot, I can understand that they can be very tiresome. I think browns are nice for typing on, but I don't do it that much, and some people lean more towards blacks or reds, or even blues if you don't mind the noise.
