    Good Poly String
    This shopper rated the product 4 out of 5 stars

    I use this as part of a hybrid bed to complement a good syn gut. It's lively and easy to use in my stringer and has good longevity.

    String Review ...

    Biphase 16G ... Good feel and pretty durable. Much easier on the elbow as advertised. My string of choice from now on

    Super String!!
    This shopper rated the product 5 out of 5 stars

    Great string in every respect. Very good feel and more durable than you would think for 18g. Better than gut in installation and over all production.

    Silky Smooth
    This shopper rated the product 5 out of 5 stars

    I use NRG2 18g in the crosses with Pro Supex Big Ace Micro (19g) in the mains and it provides me with a silky smooth blend of power, control and playability I haven't been able to replicate with any other multi - including Biphase. Compared to Biphase, NRG2 feels more plush and doesn't require the break-in period the former requires. It's silky smooth from your first stroke and when it settles in, it's so nice. Durability for my setup, despite the thin gauge, is pretty impressive in my POG 100's with a 16x19 pattern. Love this stuff.
