If Sharptooth from TLBT spoke, who would voice him

Hello,
A little different from the normal today...
Sharptooth from The Land Before Time!
-
As we know he never spoke once throughout the film, not sure why.
Anyway I've always wondered what if Sharptooth spoke and who would do the voice for him? 

So I choose 6 actors who I think could have been a great choice for Sharptooth:
Frank Welker, John Hurt, Clancy Brown, Tim Curry, James Earl Jones, Tony Jay 

So what do you think
Agree with my Picks?
or
Was there anyone else who could have been a possible choice that I haven't picked?
or
Do you prefer him without a speaking role? 

Let me know what you think!
