Seeking Hoya Rotundiflora or Chinghungensis

I’m seeking a hoya rotundiflora or hoya chinghungensis and have the following cuttings to swap:

Hoya Polyneura
Hoya Obovata
Hoya Bella
Hoya Linearis
Hoya Cumingiana
Philodendron Camposportoanum
Philodendron Bipennifolium
Philodendron Verrucosum

Would you be willing to trade the Polyneura or Cumingiana for something else?

I have other hoyas (chelsea, krinkle 8, pubicalix, memoria, exotica variegata, macrophylla albomarginata, lacunosa, curtisii) as well as sting of hearts (regular and varigated)
