I would say only do this as a last resort, if there are not enough seeders for the smaller segments. Right now thing seem generally well seeded.
The big torrents would probably be more efficient, everything else being equal -- i.e.- they would probably download faster on a strict bytes-per-second measure and help avoid stalls due to no seeders. But lots of folks might just be looking for specific eps or filling gaps in existing collections. Also, I think the multi-gig size of a complete HQ season is a problem considering that the whole thing is useless until the download is completely finished.
