Tonight while doing a round of doubles practice I hit two instances of a doubles trick. The practice routine I was doing was doubles only, numeric order ascending, and one dart per double. The first trick was D1, D2, D7, and the second trick was D14, D15, and D16. I have been hitting the doubles more consistently since switching away from incorporating the triple 20 into practice.
The darts I was using are the 19 gram Accudart Crickets with #6 carbon Fit Flight stems and slim Fit Flight Airs.
