Yes full wave is more efficient and to be honest dual rails for a SE amplifier is undeeded so yes there is really no benefit from half wave rectification in this case, but if you do need dual rail for a dc coupled output half wave rectification is required right?

Not sure I follow you on that. Almost all DC coupled amps use a centre tapped transformer and full wave bridge as their PSU.

Basically, your resevoir caps have to be twice as big for half wave. 9or if you use half wavce your wasting half your capacitance)
