The Taralay I tried at the tasting this year was pretty excellent, sap flavor of parsnip (I think this has to be the "Indochinese" flavor) and a flesh flavor of yellow peach similar to Valencia Pride.
I think its popularity will increase, as the flavors are appreciable to most, as a contrast to the Maha Chanok, which has the same sap flavor, but the flesh flavor is a deeper musky fruit flavor similar to a flavor found in durio.
Taralay is for the masses, Maha is a little too far from the norm, but still awesome.
