Strings have arrived...
Well, I strung up one of my SPB's last night with the BHBR at 57/58 in the mains and a pound or two lower in the cross. The string looks and feels almost exactly the same as Luxilon ALU Power Rough. I am going to playtest it tonight and see how it goes.
The BHB7 looks a lot like Pro Supex Blue Gear. Not sure it plays anything like that but it sure looks similar. I remember playtesting that string a couple years ago.
