I tap whichever.
Handedness does not really predict anything, the counterargument being, I use my dominant hand to hold the cards in my hand.
Same case here. I'm right handed but I only use my right hand for tapping when I've put my hand of cards on the table or when I hold no cards at all. The funny thing is, in those cases my right hand taps 90° clockwise, just like my left hand usually does. I guess I developed that habit because I like my permanents to be neatly organised, all facing the same direction.Handedness does not really predict anything, the counterargument being, I use my dominant hand to hold the cards in my hand.
