Well, me and my son both gave these a fair try over the past couple of days and we don't like them at all. The taper extends too far into the speaking length of the string causing warbling in the higher registers on both his Spector Legend and my Squier VM Jazz. Yes, we re intonated and set pickup heights to the proper level and it still happened. You can hear it acoustically. Also, even though they balance scientifically with the other strings (107-45 EXL 170BT sets), they just feel odd to both of us. We both put our old 135 non tapers back on and it just felt and sounded more correct. I don't even think we will try the 145 non tapers because I don't think our bridges will take it plus the feel should be similar to the 145 taper anyway. It was a good experiment but for some of us I think the balanced tension concept sounds good on paper but in real application just doesn't yield good results.
