In their prime, who has the most powerful left hook?

[Titing Kabayo]

Both are considered to have powerful and devastating left hooks so let's have a poll.

Left hook of prime David Tua vs anybody in heavyweight

OR

Left hook of prime Oscar Dela Hoya vs anybody in Welter/Middle weights...?

My pick is Tua in his prime..

[Golden Boy 360]

kelly pavlik

[Thread Stealer]

Maybe Bob Foster.

Tua put fighters to sleep with his left hook, Oscar staggered opponents or scored flash knockdowns with his. It wasn't a killer of a hook the way Tua's was or even Trinidad's.
