I might quite like to do this as well. Preferably 42/16 fixed but if everybody else is going "I AM ON GEARZ" then I'll probably stay at home and sulk.
I generally find that 42/16 is just the fraction too high for anything but the flatest of rides on a windless day. Not to say it's impossible but I've found that 42/17 makes a small but quite important difference. Occasionally I've wished I was on 42/18, which wouldn't have gone too slowly on the flat in a tailwind but would have eased the pain uphill into a headwind. Always each to their own and at least on a 100k you're only at it for half a day.
I like the "no mudguards no start" rule.

The mudguards rule is very rarely enforced and usually just give the organiser/control to send you off somewhere else if you want a sit down break.
