Genesis Heptonic is a third generation heptagonal shaped co-poly string. With many similarities to Hexonic, Genesis has made Heptonic a little more elastic and thus this string has greater elongation. The heptagonal shaped bites into the ball very well. Utilizing special chemical additives, Genesis Heptonic is extremely comfortable. Great power and control combined with exceptional playability makes Genesis Heptonic a great value. Players who hit a heavy ball and need a long lasting string will appreciate this gauge.
