So... my deck forms part of my barrier to the pool so I ended up making a custom rail to meet the BOCA code. I had the fence company send me 43" pickets that I mounted into my rail. I cut a dado into each rail and then made a couple hundred spacers to fill the gaps and ensure even spacing. Here's a few pics of it. It's not quite done - ran a few short on pickets, need to trim the posts, and put the cap on.
