I was at the badminton store the other day to restring my Cab 21 Special with BG-66 but the guy there was saying that they had some Babolat natural gut. So i felt like trying it so i had it strung with natural gut. Anyway, the guy was saying that he strings his rackets with natural gut main and Ti strings on the cross....... does anyone do this? And whats the advs and disadvs of doing this? thanks
