Actually I have a similar question on the topic of mis-strung racket.  I recently purchased a Arcsaber Z-slash, which as Paul mentioned in his review has a slightly different stringing pattern compared to other racquets.  Because I read the review and was curious I took it out to compare it with my old Nanospeed 9000, and found that the racquets had the string pattern.  I think the new string pattern had the stringer(whom I trusted for many years) thrown off. 

I haven’t noticed a lot of trouble while playing except the strings near the center of the racket moved apart a lot despite having the tension at around 23lbs.  I also miss my the sweet spot a lot more often than before, but hey it’s a z-slash and I kind of expect that for a while. However, I’m sure Yonex has this set up for a reason, and I’m worried if this will have any long term affects on the racket or my techniques. 

I want to know whether this makes a huge difference and whether I should bring this up with my stringer, also really how I should bring this up.  I don’t want to sound stuck and have to get my racket exactly perfect as I’m not a very high level player. Thanks!

P.S.  In Canada, higher end racket all comes un-strung so that might have also been a factor.

Is the racket actually strung incorrectly? You don't say what the issue is, just that it's different.

I think when to restring is an individual decision. My strings tend to snap before they slacken to the point I would restring anyway, so I never have to make that decision .

One piece of advice I've heard before, not sure where from, is that you should restring as many times in a year as you generally play in a week.

With all the different types of stringing recommendation by manufacturers for newer models, does it really negatively impact the game play if strung via conventional methods by a seasoned reputable stringer?

I ask cause I don't want to walk in with a stringing manual each time I get re-strung for the racquets that have a specific stringing recommendation and potentially pissing off the stringer!

Hi Wen

Not sure to be honest without looking at your racket. I've strung a few VT80's and Z-Slash's and from what I can remember it would be quite difficult to do them wrong as the single pass grommets really dictate where the next string goes. The main difference I see away from the Yonex recommended instruction is on the mains. A lot of people string down through 9, up 10 and down 11, whereas you should actually go down through 9, up 11 and back down through 10 and tie off. Which grommets they pass through depend on what racket you are stringing.

You could try and post a photo and the various stringers on the site could take a look for you.

Elisha, your stringer shouldn't be offended by you wanting to discuss the specific requirements you have for your racket, you'd expect to specify the string and tension, why not the pattern too? The stringers I know are all geeks about it anyway and will happily drone on endlessly about tension and patterns and clamps and pulling methods, to the point that you'd wish you'd never asked!
