Mechanical keyboards - anyone using one for ff - feedback please

[Headz]

Been thinking about a mechanical keyboard for general use but interested if anyone used a cherry mx blue switch for ff, very interested in your views.

Tried the qpad mk-80 mx blues in currys and love the feedback and click, but each key seems a bit wobbly, any other makes that feel very good quality?

I did look at a lot of youtube vids but rather have opinions from people using them for ff or any fps type game.

Cheers
