hi tom,
na, dont know much yet about eria's, still have at least 7 species which i havent seen in bloom.
in our region we have quite big ones and i cant take em in.
will post soon the eria ornata (dendrolirium), which is a very showy one even without bloom, and not too big either, including spike maybe 30 cm, something you could try.

well, so far your collection is outstanding!
