I recently switched from Blue Steels to D'addario Pro Steels and have noticed a much higher tension and on the D'addarios. I'm using .50 .70. .90 .110. The only difference in gauge compared to the blue steels is the A string which was an .85 with the blue steels. The tension is so much higher it required some adjustments to my action and is making playing difficult. Is it the hexcore that causes the higher tension? I've considered switching to a .45-.105 set due to the tension or Switching back to the Blue Steels which I never had a complaint about but I want to stick with D'addario because my company has a deal with them and I can buy at cost.
