Im finding its hard to use the pinky as well..I usualy just practice going from fret one thru four using each finger on off on off and occasionaly bending the string all the way down from string 6 to string 1 and so on...each string i find has a different strength in the bending so it gives my fingers a work out and finding out what strings bend easier..then i gradualy move all the way down the fret board ending near the pick up...
