Many thanks for the two sleeves of balls, so pleased to be part of the programme.
Played several rounds with the black numbered ball and have the following observations compared to the ones I normally play with.
There appears to be some loss of distance, could be due to using new 913 driver but unlikely. Control from under 100 yards is better with greater spin and so feel confident about hitting to set points on the green. They are not as durable as NXT Tours but playing conditions currently are not ideal.
I feel that it is inappropriate to comment on putting at the moment as the greens have undergone works and are not rolling truly.
Overall played good rounds compared to handicap due in no small part to the improved approach element and consequential birdie opportunities.
I intend to use the red numbered balls for the next few rounds and will report on findings in due course.
I have purchased a new 913 D2 driver and what a difference straighter and longer.
Best regards and once again thanks for the opportunity.
