Hey Mike, First of all, I'd strongly suggest going for raidz2 instead of raidz. Dual parity protection is something I'd strongly recommended over single parity protection.
You also don't mention your boot pool. You can't boot from a raid pool, so you need to put one disk aside for booting from. You may have included that already though, so I'll assume you've got 15 data disks. If you're not worried about performance you can probably create a single 15 disk raidz2 pool. In terms of data protection that's better than a 14 disk raidz pool with a hot spare, and gives you plenty of capacity. As far as I'm aware, there's nothing stopping you creating a raidz or raidz2 stripe of 15 disks, it's just that you get better performance with single digit stripe sizes. Failing that, I'd suggest going for two raid-z2 stripes of 7 disks each, with one drive left over as a hot spare.
