    is biphase closer to gut than nxt??

    which give better spin, power, control, pocketing, durability, and tension control?

    Some are going to want to answer your question as though you wrote "what is the best multi out there now?" instead. To answer you first, X-One Biphase is pretty stiff as multis go, but to get better tension maintenance, NXT Max is preferable to NXT proper. In the remainder of the NXT family, NXT Max is closest to NXT.

    the OP should read the review for prince premier softflex. I'm going to try a set and if it maintains tension like the reviewers found it will be my "go to" multi. cheaper than nxt too.

    in terms of nxt, i liked the nxt OS the best for tension holding.

    For reference, I have used both in 17g at 60# in PSC 6.1.

    So, FWIW:

    Spin: Both very similar immediately after stringing, X-1 better over time.

    Power: NXT more lively than X-1.

    Control: Both very similar immediately after stringing, X-1 far better over time.

    Pocket: NXT

    Durability: Not an issue for me in terms of breakage (I don't break strings), but it is a serious issue in terms of tension loss (see next). NXT does fray fairly easily.

    Tension: X-1 far superior in tension maintenance. NXT plays very nicely immediately after stringing then exhibits serious tension loss with play time, leading to a fairly substantial trampoline response.

    X-1 always gave me arm problems as it has a certain amount of poly in it i believe, it felt stiff to me, and i steer clear of poly's. NXT or Yonex 850 are the best multi's IMO.

    I never felt X-1 was in any way stiff...very comfy for me at 57-58 lbs in my RDX Mids where I used it most often. I preferred it over NXT, felt it provided very similar results w/better tension maintenance and durability.

    Spin, power, control, pocketing are all close enough that it wouldn't make much difference which you use...in tension maintenace and durability there was a bigger difference.

    I'd go w/the X-1, and string it 2 lbs less tension than you would string NXT, if you've strung NXT in the past. If you haven't, try mid-point on your racquet, or maybe a lb or two under...

    According to the Sept 2006 USRSA string test:

    String, Type, Gauge, Stiffness, Tension loss
    Wilson NXT Tour 18 Nylon 1.24 209 9.53
    Wilson NXT Max 16 Nylon 1.34 211 9.71
    Wilson NXT Tour 16 Nylon 1.31 219 8.98

    Tecnifibre X-One Biphase 1.18 Nylon / Polyurethane 1.19 181 8.96
    Tecnifibre X-One Biphase 1.24 Nylon / Polyurethane 1.28 192 10.12
    Tecnifibre X-One Biphase 1.30 Nylon / Polyurethane 1.31 192 10.08

    Tecnifibre NRG2 16 Nylon / Polyurethane 1.31 197 8.05

    Seems like Tecnifibre is softer.

    These stiffness ratings are often, well, "counterintuitive", shall we say? They often don't prove out in practice.

    And if you're used to another string category--poly, say--degrees of softness seem banal.

    Poly in a Biphase x1 multifilament string? Not!

    I'll take an objective measure or a subjective measure any day.

    How about a consensus of peers, then? I'd think you need to reconsider, based on what the measurement standard does.

    psp2, oh yes it does! See above post for string composition etc.

    Are you talking about the polyurethane HPC in the composition? This isn't the same polyester monofilament that we call "polys".

    Exactly....In the science field, poly usually means polymer and it just means 'a lot' or in a more definitive way, Polymer is a term used to describe large molecules consisting of repeating structural units, or monomers, connected by covalent chemical bonds. The term is derived from the Greek words: polys meaning many, and meros meaning parts. e.g. polyurethane, polyethylene, Polystyrene, Polypropylene, etc.

    In the world of strings, when people say poly, it usually refers to polyester and the confusing thing is polyester is 'synthetic(or man-made)' fiber made by scientists in 1953 so the way the tennis people categorizes Synthetic, poly, multi is all confusing especially if you studied (organic) chemistry.;)
