The choice of raidz1 versus raidz2 is another matter. Given that you've already got raidz1, and you can't (yet) grow that or expand it to raidz2, then there doesn't seem to be much point to having the second half of your storage being more protected.

There is no harm from using a raidz2 vdev even if an existing vdev is only raidz1. If raidz2 is an available option then it is wise to choose it. Of course starting out with raidz2 would have been even better.
