Let me begin this by saying I am not starting a new campaign in the immediate future, or even the not so immediate future. I have enough on my plate with my ongoing ACKS campaign (and possible side campaign therein) and my DCC RPG quasi campaign that will be run in Arcs. That being said, Saturday Night's games session reinforced the idea that newbie funnels are fun and build a true bond with players and their surviving PCs.
What was meant as a quasi-goof: running a funnel in ACKS with characters that would would become the regular PCs' henchman went better than expected. The survivors had value. The players were invested in them. The characters now have a bit of a back story and history.
They will not be one dimensional at first level (not that my players make one dimensional PCs - my group is fairly deep in the roleplaying). This is a side effect of the funnel that I hadn't expected, but having run a DCC funnel and an ACKS funnel, I plan on starting my next "D&D" style campaign with a funnel.
Of course, depending on how my current games go, that could be months or years in the future.
Remember, "Fun" is short for "Funnel" ;)
