TESTERS ANNOUNCED! BirdieBall Putting Mat in Past Testing Opportunities Posted September 18, 2020 First Name and Location: John--Clayton, NC USA How do you keep your putting sharp through the winter? A little practice at the course green but mainly just putting on my hardwood floors which doesn't give me good reads or true roll at all :( Current/Past Experience with putting mats--they have crinkled up in the past or the carpet just gets loose and has been....bad to say the least. Not good experience translating it to the course. Go to www.birdieball.com and tell us which speed green you'd want to test--Medium 10-11...Im right on the verge of Championship but most courses I play around here are medium and this would translate better to feel on the mat vs feel on the course.
