Thanks for your feedback.  I'm going to give it another try.
I used to run ZFS on top of geli but I had kernel panics.

I changed the providers to normal non-geli disks but still had
panics.  I found out later that the panics were kernel memory related
(kmem_malloc) since ZFS wants a lot.  I increased two of
the kernel memory parameters and haven't seen a panic again.

vm.kmem_size: 512M
vm.kmem_size_max: 512M

I guess I'll have to try the geli disks again now that the
memory has been increased.
