>> WAVEY is also used primarily for heavies going "north" eastbound to the NATs. <<
Out of JFK/EWR ? The Caribbean tracks yes, but not the north atlantic. Even routes fairly south, like over SLATN, would file via SHIPP. I don't think I've ever seen a route to a NAT track via WAVEY ? GREKI, MERIT, BETTE, HAPIE are the standard ones.
