Other than the obvious difference of TBHB7 being a shaped string how do these strings compare? It looks like TBHBZ is much softer with a little less tension maintenance. Would you string these strings at the same tension full bed? I’m playing TBHB7 at 48lbs in the Wilson 6.1 18x20 and getting ready to string up some TBHBZ this morning. With it being much softer wondering if I should stay the same tension or go up to around 50.
