Well, this focus on mono seems to be to be all about getting the lead to dig in, which physically speaking, could be achieved with the same diameter braid or maybe an extra long length of leader.
Not sure I could ever go back to mono straight through - just seems so antique.
And as for casting with braid, the shore boys seem to manage fine at 100+ yards, so I reckon I'll be ok at 30-50. Happy to be persuaded otherwise though.
