Odd, I found them to be quite lower tension than most other strings.
I'm now using these on my Lakland 5501..nickels 40-100 with a .130, a custom set from Bass Strings Online. Next time I will get a .135 though. These are great strings and if they last a good while I'll be sticking with Foderas. Very impressed.
