Giant avocadoes, are they always blee-worthy?

[NotQuiteCockney]

Last week I bought a lovely-looking giant avocado, maybe twice the size of a normal one. Not hass. It ripened up fine, and I made guacomole with it today, but the insides were wet. Not nice and greasy, but wet.

Are they always like this? I find non-Hass avos a bit of a crapshoot ...

Not always like this. I've sometimes had them and they were wonderful (green skinned efforts).

Maybe the variety?
