But see Acta Crystallogr D Biol Crystallogr. 2006 Mar;62(Pt 3):227-38. Epub 2006 Feb 22. on why thin shells aren't necessarily the answer.
And note neither program mentioned, dataman nor sftools, will allow you to extend the set of shells to higher resolution if you want to follow the practice of preserving your existing R-free set. Ian Tickle has argued there is no need to transfer the free flags from one data set to another, so that may not be an issue.

You can also pick thin shells with SFCHECK and with 12-fold NCS the referees will likely not be kind if you dont!!! -- Mark
