    Hi guys,

    Just bought a Dunlop Aerogel 5 Hundred Tour at a good price (fairly obsolete now but a stick with a great reputation) and it is factory strung as one piece. I would prefer to string 2 piece and was wondering if anyone had the 2 piece pattern. I've been advised that the last cross tie off is at 10T but that grommet seems a little small to accommodate 2 strings. Any information would be appreciated. aussie.

    Jim, mine is the non 4D 5 Hundred Tour but I think the pattern still fits. I tried putting a scrap piece of 1.35mm syn gut through 5T (the last cross tie off) while the factory 1 piece is still installed and it fits through no problems. Could you just confirm that the Aerogel 5 Hundred Tour pattern is the same as the 4D version quoted above. Thanks, aussie (John)

    The non 4D tie off is 10T

    If the grommet seems small you can take an awl and lube it with chap stick,. and SLOWLY twist and insert it into grommet to slightly enlarge grommet to make it easier to tie off.Do this before you place any string into the grommet.

    Thanks guys. Yes, the 10T tie off for the last cross matches the info I had, but let me tell you it is an incredibly small grommet which will take a fair bit of enlarging. The 5T grommet for my Aeorgel 500 Tour is closer to the exit grommet for the last cross at 7T and makes much greater sense to use it as the tie-off. Do you guys see any problems with using 5T as the tie off instead of 10T given that it easily accommodates 2 strings and is the recommended tie-off for the 4D version? Thanks for your advice btw - it is much appreciated. John

    5T should be fine.
    Who knows? Perhaps it is a transitional racquet with the 4D grommets?

    It is very easy to determine the correct grommet for tying off. With no strings in the racket look for the larger holes. For instance looking at this grommet strip:

    it is easy to tell the tie off is the sixth grommet from the left.

    Which is why it is difficult to comprehend why the recommended cross tie-off is 10T which is a single string grommet. 6T (the mains tie-off) and 5T are the enlarged grommets, but 5T is not the recommended tie-off for the Aerogel 500 Tour but is for the 4D 500 Tour. It's almost as though Dunlop realised they made a mistake in stipulating the 10T tie-off for the AG 500 Tour but then got it right with the subsequent updated model the 4D 50 Tour. In any case, I'll use 5T as the cross tie-off which is adjacent to the mains tie-off at 6T. Seems to make a lot of sense.

    Everyone makes mistakes. Even the USRSA and Manufacturers. If 5T and 6T are the enlarged grommet holes they are you tie off locations. If a USRSA member would raise that issues with the USRSA I am sure they could get it corrected.

    Here's what I think happened. Since your racket starts and ends at the throat of the racket the main string going through 6T lays on one side (towards outside of frame) of the grommet leaving the the inside of the of the grommet hole open for the string to be tied off. 5T is just the opposite the string coming from 4T is held on the inside of 5T while the 5th main holds the string on the outside of the grommet. This makes the string go across the grommet blocking it. If you try to insert a large and/or soft string through the hole it is difficult. Also you are tying a cross on a main string would could cause problems. [B]NOTE:[/B] There are reasons to tie a main on a main and a cross on a cross. So the designer designs the racket to one way and the plant that builds the mold differently and changes the racket.
