You should take a look at the ZFS best practices guide for RAIDZ and mirrored configuration recommendations:
http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide Its easy for me to say because I don't have to buy storage but mirrored storage pools are currently more flexible, provide good performance, and replacing/resilvering data on disks is faster.

Thanks! By single drive mirrors, I assume, in a 14 disk setup, you mean 7 sets of 2 disk mirrors - I am thinking of traditional RAID1 here. Or do you mean 1 massive mirror with all 14 disks? This is always a tough one for me. I too prefer RAID1 where redundancy is king, but the trade off for me would be 5GB of 'wasted' space - total of 7GB in mirror and 12GB in 3x RAIDZ. Decisions, decisions.....
