On our '13 RT-L, we share the Spyder, my wife laughs at me when I use two-hand procedure to shift it to Reverse. Right thumb on the R button, left index finger to hit the - paddle. I try to user left hand but it's hit and missed. She only uses her left hand to shift to Reverse and it works every time for her. A side note: my wife's height is 4'11"3/4, typical Asian woman.
