Coastie, the slot idea may also give you a more natural--and nearly invisible--splice point.
Edited..Putting a Pergola (Trellis) over my back deck. Looking for some input please...

Coastie,
Or, for the roof boards, don't use pressure treated wood, but instead some other wood that is naturally water resistant and stands up to being outdoors without the need to stain, and that is already seasoned. Maybe cedar or somesuch???

how bout using 5/4 size TREX (psuedo-wood) for the top boards and making the slots at an angle? I know we're getting pretty fancy here, but you asked !
That would give you shade and you would NEVER have to worry about warp and preservative.

I've seen Trex (and other fake woods) on decks, and have been greatly underwhelmed. The appearance isn't very good, they fade (they all claim they don't, but they all do, very significantly and very quickly), and some (I forget if Trex is one) are prone to warpage. And their cost, when compared with pine or even cedar, are exhorbitant.
If you already have a natural wood deck, I recommend sticking with a natural wood pergola. Anything else won't look right. Doesn't even need to be the same wood, particularly if it's free-standing.

Bill,
First, let me complement your deck. It is a very nice layout especially when you consider the elevation of it. Very nice job.
I do prefer real wood and like you have found the artificial wood to be not appealing as well as weaker when it is cut to the same thickness as real wood. It does require additional support. Which, would not be what I would want to do above my head...
I am still flying around the country, will try to get pics put up as soon as I can..

Thanks for the comments on our deck. It's been up for 9 months now, and we absolutely love it! The only problem with it is that it cost enough that we now can't afford a decent set of patio furniture to put on it! 
Playing devil's advocate, one potential positive of the fake wood is that you might be able to find it in 30 foot lengths or longer, thus possibly addressing your span/splice issues. I don't know what lengths it comes in--I've never had reason to look into that. If that turns out to be a concern, it may be worth another look.
