Should the UK Champs decide the 6 UK teams for the WHBPC?

swiss round is the best and fairest format, but the wheel or seeded groups are second best. the only issue is that the seeding (if done) in this case must have been done purely arbitrarily because there is no means of seeding at least half of the teams in the tournament

This argument is flawed, swiss-style again tries to get the best teams to play the most games, it's completely bias towards finding the best of the best, which means if you lose, you're more or less out of the running.

The wheel system allows everyone to play a set amount of games, regardless of the outcome of those initial games, the aim being to allow everyone some tourney time. This is an direct alternative to swiss-style as it is more-or-less impossible to provide early stage comparison of the teams (without a massive back-log of team seed value/points).

The UK champs will be a fairly "unfair" tourney as your initial games may be too easy/hard, because we're single elim after the "unfair" seeding, you may find that you place badly due to bike malfunction, etc.

However, I'm all for it, it's the best we've got, live and learn, bring it, polo.
