We all know that when the FT worlds goes to another country they make the rules up to suit thier own shooters. The U.S one being a particular joke.
I know that there are a concrete set of WHFTA rules so that should be fine but i also think that we wouldn't get that many UK travelling shooters. I do agree with the OP to a point as our European friends are the ones always doing the travelling.
Personally i would travel if the HFT worlds was in another country.
