Fuel breather mods

I haven't read ALL the posts on this topic, so flame me if you must!
The primary requirement is to prevent a petrol smelling garage (and significant fuel loss). The other requirements must, of course, be satisfied as well - namely being able to fill the tank in a reasonable amount of time and allowing air into the tank to avoid fuel starvation. The other common claim of the Lotus system - fuel not spilling out when driving upside down - doesn't really apply to me as I have a cabriolet. I would discount it anyway in preference to the other advantages.
I spoke to Sean at Spyder about his system - one crossed over pipe leading to the filler neck, the other blocked off - and it does indeed rely on the filler cap not being airtight. I asked him what if it is and he said it isn't because there's a small hole in the cap and there is. I couldn't understand why he still takes the breather opposite the filler over the roof but I can't anyway. Logic (mine says why not just take the nearest breather tube to the filler neck? EDIT: with same bore tubing - what type? Gasket compound? And sender unit gasket to check.
Keeping in mind that all the filling stations in France are level (there's probably 'n' number of laws making sure they are) I ask you, Lotus lovers, why not?
