To combat one of the biggest downsides of polyester, tension loss, the Dyreex POLYROCK is pre-stretched. So, it should be noted that the loss of tension is almost nil due to its modified copolymer-based structure.
It is a firm, durable and low-powered co-poly that rewarded powerful strokes with remarkable precision and extremely easy access to spin.
