I have some from another brand that say they're equal tension...I don't know if they're similar or not, but mine are definitely harder to bend on the some of the higher strings...probably going to switch back to more standard strings soon.
That's the only problem I've noticed though, and if the D'Addarios don't have that issue then I don't think there's any reason not to try them if you want to.
I didn't have to do a full setup to try them either.
