1. First Name and Location Russ, Woodinville, WA 2. How do you keep your putting sharp through the winter? Indoor carpet, course practice greens. 3. Current/Past Experience with putting mats I have had a few, but the quality has been poor and they were narrow strips that didn’t setup or store well — essentially more trouble then they were worth. 4. Go to www.birdieball.com and tell us which speed green you'd want to test Fast. Home course greens tend to roll fast with a lot of movement.
