Cydrome Leader fired this volley in news:nvalkp
:

What were some of these tricks?

A few of them include putting 'kinks' in the inner part of the curve, in
order to reduce the radius.

A _good_ guy will put all the kinks in the direction such that the folds
don't interfere with pushing a bundle through, or sucking a rat through.

But as long as the kinks don't use up enough internal volume, it's
usually still pretty easy to push wire through, because the wire wants to
follow the o.d., not the i.d.
