it is rather difficult to tune in on the higher power level of this string. coming from poly mains i find that the recommendation to string lower (of course related to syngut) is somewhat misleading. i haven't played natty gut for quite a long while (with the exception of two hybrid sets last summer, when i had to play it in the crosses), but i think that from a certain perspective it has a ng-like behaviour - at medium pace you think you finally got it under control just to find yourself that facing a hardhitter you spray balls all over the place. the power level relative to incoming ball speed (and spin of course) is completely different than what i'm used to with poly mains - i can keep heavy incoming shots pretty good under control with poly mains but i do still have to find my range with the mgzx - at 22kg (48lbs) it works better than my initial hybrid at 21kg(46lbs), but not yet at the level i would like it to be. as a matter of fact, i think that it is also a quite temperature sensitive string - last time i played the temperature outside was around 17°C and i was playing a hardhitter. surprisingly i had little trouble, even returning first serves. it's a pitty it started raining (again) after just 15 minutes, so i was not really able to complete a match under those conditions.
