Default Which Gap is the best?

I've read a number of threads about the proper gap for our standard 2.4 lt. PT's, and it's really like looking for a dog at a shelter that has about ten really cute puppies, on their best behavior. All of them are cute, of course--but which one do I choose?

I've seen people here recommend 50, some 40, some 35 thousands. There is a great deal of difference between these gaps. I want my car to smog in a few days after I change the wires and plugs, so which one is best for just regular old city/highway (about 70 mph, tops).

Get your vote in--and tell me why? Common sense is telling me to gap at about 40 thousands--and I hope the plugs come pre-gapped, cause I hate bending those electrodes. It just seems like a form of molestation, if you know what I mean ....

Thanks, everyone. I just bought Champion Copper-Plus Plugs. I'd go fancier, but I'm about to smog the PT and my daughter's Del Sol just failed the test, so I'm a bit paranoid. I'm going to go with a .45 gap and see what's what with that. Haynes says .48 to .53, so I'll fudge a little, I guess. I haven't bought the wires, yet; but I'm just going with the Belden? at Napa Auto.

Do .040 on the gap or what ever the tag on the hood says.
