You should have one funnel for one purpose.
For example, if you are attempting to get the PNC to book a consultation, you should run a "Billboard" funnel.
If you are running a nuture campaign with a lead magnet, you should run a Legal Lead Generation funnel.
What it boils down to is that if you are asking the PNC to do more than one thing, the conversion may go down. This is why running paid traffic to your main website is a bad idea. It allows the PNC to search the site, click all these buttons, and get distracted from what you are trying to get them to do.
