i recently switched to head ultr tour 16l @ 55 for the mains on my flxpt tour and nxt-16 @ 58 on the crosses as i was breaking strings on straight nxt and didnt like the feel of straight ultr tour. it plays good except the nxt keeps fraying after a week or two ( i play 3 times per week). the ultra tour lasts fine...... any suggestions? i have heard luxicon big banger alu power? i am a 3.5 SW fhd, 2 hd bhd player.
