Tom, your last comment is actually the reason I was considering backup sets as a top contender for long term storage. Generate a backup set, the owner signs for the tapes, and they're gone -- reserving library space and volume ranges for data that is actively used or needed for DR.
The inability to move a backup set to a new generation of media, as Bill noted, is something I hadn't considered!

OTOH, here's what I've done: 1) set up archive copygroups with retentions of 1 year through 7 years (seven groups) all pointed to the same storage pool chain (disk and tape). 2) treat the storage just like everything else -- one copy on-site, and a copy pool for off-site. I run reclaims as required and otherwise exercise the LTO media once or twice a month. If I were to do the backup set process, I'd make bloody sure that the owner of the data had the tapes AND HAD SIGNED FOR THEM so if they got lost or damaged I wouldn't be in the loop.
