How's this for a quick fix to Puck's inconsistencies between V2 appearances and other appearances before and after:

During the entirety of V2, Puck was pretty much brainwashed. That brainwashing may have included his perceptions of his powers. He was knowcked around easily during V2 because of the brainwashing. With that effect removed and his mind restored, he has "resumed" his compressed rubber abilities, as seen when smacked by Juggernaut.
