I just looked at the pic of Hepta Twist and I think u are right. The edges are diagonal and they dont sit perpendicular to the gut mains so they may not "dig in" so much. My only concern is that all 3 reviews I read mentioned that this string loses tension quickly after about 4 hours of play. Did u find this?
Does anyone have the link for TW's friction testing?
