If you will be using stock as thick as shown I'm pretty confident big M&T's will be all that's needed. As the stock gets thinner the racking resistance will be lessened and you'll need a stretcher at some point. Just guessing, I think with 8/4 stock you will need a stretcher, but not at 12/4 or thicker.

That thing is massive! And, it looks like a(?) through tenon at the near end. Something like that requires a few beasts just to move it. Nothing else required. I saw one about 30 feet long.. I think it was parked on some outdoor stone decorations (balustrade?). You would kill the impact with a stretcher.

You could always add a steel rod stretcher afterwards with no great difficulty. Or you can go to a local iron railing company and have him make up something more decorative.

Thanks for everyone's input. I think I'll just leave the design as is and save myself the work. It wouldn't be hard to add a stretcher afterwards if the thing didn't prove to be rock solid.
