    My stringer/pro says that he is have issues getting both strings through the shared holes on my Dual G 100. He is getting the string jobs done, but says that it is a nightmare. He is a experienced stringer/pro. I was wondering if you all might have some tips for him. I am stringing a hybrid of Isospeed Cream and NRG2 16.

    What about it is a nightmare? Passing the NRG2 through the shared holes - once the mains are installed? That's the only thing I could think that could cause a bit of an issue (frankly, I'm surprised it'd be much of an issue at all for an "experienced stringer/pro").

    If this is the issue, I'd cut the tip of the NRG2 to a sharp point. If that alone didn't work, I'd try a dab of super glue on the very tip, as NRG2 is fairly soft.

    No issue whatsoever. Strung them mostly hybrid with poly tour mains and super G crosses. No difficulties. I do use a yonex loop when tying off the mains (after 6th main, I first tension 8th main, go back up to do the 7th main and tie off at 6H)

    Thank you for the reply's, I do use the NRG2 in the mains if that would make any difference. So I assume am1899 that cutting a sharp point on the cream might help.

    Beepee1972 I assume that using the Yonex loop would have nothing to do with feeding the string though the shared holes. I that correct?

    Yes, if the NRG2 is the main string...then this REALLY shouldn't be an issue. Feeding a poly string through shared holes shouldn't be anything resembling a nightmare.

    As for the Yonex loop - yes, this technique does involve the shared holes in this case. After installing the 6th main on either side, you'd be skipping the 7th main, installing the outside main (8th), then installing the 7th main last, followed by tying off.

    There are 6 shared holes top two crosses and the bottom cross. If you preweave the top three crosses before you tendion the outer mains that eliminates the top four because it is easy to pas the string through with no tension. Then you have the bottom cross to contend with. If your stringer is having an issue with the bottom cross cutting the NRG2 to a point and using some lubricant should resolve any issues he may have. Also placing some scrap string in the bottom cross grommets until you are ready to weave the cross helps too. If the scrap string has a point cut on it you canuse the point on the bottom cross to push it through.

    Yes, per Irvin's point...the top couple crosses could be pre weaved to mitigate this issue. But one shouldn't even have to do this if they didn't think to, or simply don't want to. There's nothing here that should equate to a "nightmare."

    I had a bit more trouble with "aligning" mains and crosses when pre-weaving the first 2 crosses. That is why I always finish my mains first, before I enter the crosses with this racket. I do like to use an awl carefully to create a bit more room (guidance) for the cross to enter the grommet.
    And I make sure that I pull the last 2 mains down towards the bottom of the frame (where it is mounted on the machine) when I apply tension.

    I will call my stringer tomorrow and ask where the problem is and rely all these good tips. I think one issue is that in our rural area hardly no one hybrids so he usually strings one piece and I am the only one that has a frame with shared holes. He has given me some notes to keep to give him when he strings. The notes say
    To Main 6H
    to cross 9H 7th
    Share 8T4
    7H
    8H
    Do you all maybe see a possible issue with this.

    No.

    Edit: Yonex calls for the bottom cross to be tied off at 9T (not 7T, as your notes indicate). But it shouldn't matter all that much - either location should work fine.

    All the other notes you provided seem in line with Yonex stringing instructions found here:

    This is the 1st Yonex racquet I've seen recommend one-piece stringing. 1st since the 90s with shared holes. Any other current racquets with shared holes?

    Umm...Yonex doesn't recommend one piece stringing for this frame. Tying off the mains at 6H and 6H, as noted and depicted...implies the mfg recommends the racquet be strung 2 piece. See here:

    http://www.yonexusa.com/products/tennis-stringing-instructions/

    Shared holes are reasonably popular now. There's a bunch in Head's lineup, all of the Burn spin effect frames have shared holes, and I believe one of the Wilson Ultra frames has shared holes as well. There's many others that just don't come to mind at the moment.

    Frankly, I don't pay much attention to TW's "String Pattern" data. Sometimes it's misleading...and sometimes it's outright wrong.

    Many frames on the TW site say 1 piece stringing that does not mean you can't string two piece or that the manufacturer recommends that particular pattern.

    I strung a Head Graphene XT Speed Pro (shared holes 8 & 9) that I put a new set of grommets on... had kind'da the same problem. The cross string were Prince SynGut/Duraflex 17ga... much softer (flexible) string than a poly. I took a piece of poly (Luxilon ALU Power 16) angled the point, dipped it in my candle (wax) for lubrication and it slipped in. However that still didn't do it for the Prince. I will back in with the Luxilon and did a rounding motion (hard to explain) which made a bit more room, which worked. The mains were Luxilon ALU Power rough 16ga.

    I actually find the shared holes on recent Head frames easiest, as there are defined cut outs on the grommet to ensure that strings that pass each other on the outside of the shared holes are stacked - one on top, one on the bottom. So long as you don't "mix" these channels, it's hard for me to see how there'd be a problem. For example, if your second to last outside main feeds through the low part of the shared hole channel, make sure that you go through the low part of the channel of the grommet on the way to the outside main. This tactic ensures you won't have any cross overs on the outside of the frame.

    If you're having any trouble feeding the string through Head shared grommets:

    If you're feeding the string through the high part of the channel, angle the string up. Angle the string down if you're passing it through the low part of the grommet channel.

    Why 4 pieces?
    Why not just 2 pieces?

    "Lendl patterns" require more than 2 pieces...could be 4, could be more, depending on how it's approached.

    Especially if you string those crosses 1st so not to run out of string

    10 of those 29 crosses must be in another dimension since the frame only has 19 physical holes for crosses. :p

    Nope.
    Done it many times with only 2 pieces... as well as only using the designated tie-off locations (i.e. not opening up/widening any other grommets).

    We have had this discussion before. Actually it is only two pieces of string and four knots.

    Require was the poor choice of a word on my part, sorry. Yes, of course Lendl pattern can be done in 2 pieces. But, depending on the racquet, there may we'll be some rather lengthy runs of string on the outside of the frame (something I generally try to avoid...probably my OCD about aesthetics). So, in my head...depending on the racquet...a Lendl 2pc doesn't necessarily occur to me naturally.

    Irvin what do suggest as a lubricant, would just Vasoline work?

    I use paraffin wax, some people use chap stick, and I guess Vasoline would work but I'd rather use a water based lubricant.
