I believe only bureaucrats impose rules for no particular reason other than camouflage their agendas and justify their salaries. So assuming no-one is getting rich on Extreme Field Target, I believe it safe to assume no-one here is interested in adding superfluous rules.
Having been involved in more rules-making/evolution than I ever cared to, contrary to what some seem to believe, everyone should understand that rules come about to address real issues and situations; either forecast, or as issues dictate solutions.
So rather than anyone jumping to conclusions that rules are unnecessary, or just a few rules can address any competition beyond tiddly-winks, much less EFT as it grows from infancy to awkward adolescence to maturity, the most we can hope for is to cover all the necessary bases with as few, simple, succinct, and unambiguous rules as possible.
I'm still not sure this thread has settled whether or not bum-bags are allowed in EFT competitions. But employing one rule that seems virtually sacrosanct might prove its worth at this particular moment in Extreme FT time; that being Match Directors' option... correction, luxury, of running their events as they see fit.
As it seems bum-bags are in danger of becoming a casualty of a larger, elephant-in-the-room agenda, allowing bum-bags at TEXtreme Field Target might help set sensible precedent for healthy growth of Extreme Field Target.
