It has more spin than any yet made. It has perfect connection to the bed. It has more power than vs team 17g gut. It has better tens. maint. than any yet made. It feels great on groundies and volleys and serves. I guess if they made a barb wire/gut string, twisted, squared off, with insane bite and touch/power. Not done yet. You either get ok spin with the tour bite/barb wire, for a short while, or ok touch/power with vs team for a longer while. Maybe I should try hybriding the vs team 17g with barb wire both ways.
