Super dwarfs basically are referred to just one locality, though I forgot which one, and generally only reach 5'-7'
The other dwarfs depends on the locality. Jampeas are capable of reaching 15'+. Kayuadi island dwarfs I think can get up to 10', so I hear. Selayars get over 10', I'm pretty sure.
I'd probably go with something like a male jampea, if I were you.
