Slightly old news, but pretty cool.
That 0.02 difference between the high E and B in 9-42 tends to irk me. The E string would always be harder to bend/do vibrato on compared to the B, regardless of how much I would work on the technique and no surprise some guys prefer an 8 for their high string
Really needs to be a 0.025/0.03 difference for more even bending.
The 9 as an E and 12 as the B in the 120BT set is much more balanced and even.
110BT looks good for D standard for my tastes too.
