Ninja Vanish alternative

I’m sure there are MANY pieces of advice out there, but anyway…

Do you use your whole palm or just one or two fingers for the hold before the slack?
I’ve been using my whole palm, and can land it about 1/2 the time. One finger pinch is worse, much.

I’m doing something wrong, and keep avoiding this trick due to my inconsistency with it.  I’ve been yoyoing quite a while and this trick has given me trouble :-\

Tricks that require neutral tension are tedious when you miss them. This is a particular trick where  one on one with someone who’s good at slack and whip tricks would bring benefit.

Edit:

Anything open a door for you?

I learned the NV variant just as instructed on the yotricks tutorial, issuing my whole hand. Now I just use one finger. It’s pretty much the same motion as the regular ninja vanish, just… slightly different. Just shot blind until you start landing it consistently. It’s hard to understand what the string is actually doing, it’s more about muscle memory for me.
