Hey everyone, I'm on LF Pro Shop staff and these were my results.
Singles: 614 - Big Hurt (Played 10-13 at the arrows for the whole set)
Doubles: 486 - I tried almost everything in both bags lol (Judgement, Higgs, Big Hurt, Jacked, Korrupt & Exodus Pearl) - I was all over the place and just not making good shots.
Singles: 735 - I had an epiphany. Moved in with the Exodus Pearl (which I experimented with in the last 3 frames of the 3rd game in doubles) and played in my comfort zone (18 at the arrows to about 8 at the breakpoint) - 279-235-221=735 - My best set at the Nationals. Great showing for Lord Field. Happy with that set as I am sitting at tied for 78th in singles. Hopefully that will be a nice check
