I've been enjoying natural gut setups for the past month and a half or so, and played with gut/poly which lasted a good 15 hours before the poly half of the hybrid started to feel uncomfortable, and with full poly I play about 6-8 hours before cutting them out. Turns out, with an 18x20 midsize frame and an eastern, semi-flat forehand I'm not much of a "string breaker."
For me,
15 hours with Lux gut and any typical poly (e.g. Head Hawk) is roughly $29 with half sets of each, and at 15 hours it comes out to $1.93 per hour. If I switch the gut to Legend, it goes down to $1.36(!!) per hour.
7 hours with a full bed of poly (e.g. Hyper-G) comes out to $1.70 per hour, and at best, for my preference 8 maximum hours it averages to $1.50 per hour, and with good value poly strings like Tier One Firewire boost, it comes down to $1.12 per hour at 8 hours, which is still very close to Legend/Poly, which can be brought down by going with a value poly cross as well.
So if I think about it like this plus the long term arm health benefits, natural gut is without question a great option, if not the best option. With this kind of value, perhaps
@ByeByePoly can be convinced to join the "gut snob club" except it's actually not snobby, it's priced very competitively for the number of hours
I just received my packs of Legend I ordered, and my last hybrid of gut/zx did not turn out well because I don't have a way to prestretch the zx besides the dropweight method, and that ended up locking up the stringbed due to the zx digging into the gut's coating during the stringing process. Quite disappointed because I thought that would be my best setup, and I don't know if I have the discipline to prestretch the zx through other methods. So now I'm getting interested in some of the gut/multi hybrids, especially if multis like V pretty much functions as a slippery supporting cross string. Isospeeed Professional Classic also comes to mind based on reading
@Toby14 's preference for this string with natural gut so I'll definitely keep following these threads and will likely try one of these combos out in the near future, you guys are doing God's work
