Long range uppercuts should you thro them like a long range hook or more like a cross

[SugarBoxing]

A long range hook is a hook with an elbow bend larger than 90 degrees, think Tommy Morrison he loved to throw long hooks as did Sugar Ray Robinson. Like a right angled hook the arm stays rigid at the elbow and stays in place.

With a right cross however the arm "unravels" much like it does with a straight right or a jab. (or at least as far as I know)

Does a long range uppercut unravel like a cross or does the elbow stay locked in position from start to finish?

Long range cross is more like a hook
Uppercut is uppercut

There is no way you can interchange the technique.
