I know what you mean, I also had a hard time at this fishing hole, yes A is the one to use, what I finally did was the instant it starts to vibrate I hit the A once that seems to stop the advance of the green then I start tapping the A I continue until I see the orange color then stop and the second it turns green again start tapping the A again. you have to really watch the the fish hook up in the right hand corner, and most of all be patient, tap, tap tap then wait then tap tap tap again. Good Luck.
