3 weeks ago, I have put this into test.
After a bad 1st 9, I decided to calm myself down and just play safe by tee-off softly - just keep in play though drive is oni 170-180m and no more spectacular shot when in trouble.
1st 9-hole: +15
2nd 9-hole: +9
Have yet to put it into 2nd test on full 18-hole.
