Postdoc or Job?

I currently have 6 years of teaching experience and a PhD (in mathematics if that helps). I am left wondering where to go next. I would like to try out industry and the private sector (they pay better), but I don't want to lose the ability to come back to academia in the future. Obviously, to stay in academia requires publishing and research on my part and maintained interest in a particular field (maintained contacts and joint papers).

So, assuming I am capable of doing research on my own time, should I do a postdoc and then a private sector job or just get a private sector type job?

In other words, several years down the road, what looks better for an academic position:

A = (6 years teaching) + (PhD) + (a dozen or so publications) + (2 year postdoc) + (2-6 years industry)

B = (6 years teaching) + (PhD) + (a dozen or so publications) + (4-8 years industry)

This is important in the sense that PostDocs (oddly in my opinion) require "fresh" PhDs. Many specifically require the PhD within the last 3-5 years. So it seems imperative to get one while you can. Right?

On the other hand, I have also heard the argument that people get PostDocs because "they are not quite ready to be on their own yet". Or PostDocs are used to gain more contacts and learn what it is to be a "professor". As such, any high paying, senior type position would look better than a PostDoc. Even an internship would look better than a PostDoc. Right?
