>...pros and cons of using Js vs Ks for offsite tapes. ... Offsite storage charges are often based upon the quantity of tapes, which tends to argue for evolving to 3590 K tapes for offsite use. Ian's excellent observation on relative 3590 K fragility should be a factor if you have butter-fingered operators or the arrangement with the offsite vendor includes picking individual tapes, rather than whole bins, for return to site.
