I'm a little confused about the names of grabs and direction.

If I do a back roll on my left tack and I grab the "front" on the board with the front hand, I call that a nose grab.
If you do the same grab and same hand but later as you land toe side. Is that a tail? It feels like a tail?

So dose the names of grabs change if your landing toe or heal side?

Iv been trying to land this grab with back to wrapped.
