OK, the second time I spoke about geometry, I was right.
But the first time I took things the wrong way.
So, as I thought (and hoped!), my estimations were pretty
pessimistic (by several times on the string's rupture 
load). Good news, huh?

Thanks for those of you who kindly replied me off-list...
