I've been using babolat natural gut on the cross and alu power rough on my mains for quite some time. But now, I'm not willing to spend the extra money for the natural gut. I know that this a popular hybrid and I'm hoping that you guys have made the same switch that I have because I need some suggestions as what to use next. I need to make a wise decision because i break strings every month or two, so I will be stuck with this string(s) for a little while. Thanks for the help.
