I also find the Fenders to be great and honestly go back and forth based on what is cheaper at the time. I change strings weekly, so cost is of importance to me.That's their best qualities that keeps D'Addarios the best selling strings in the world. I happen to like EXL-170BTs best of the XL series. Also the D'Addario made Fenders are excellent too. I have moved on to the new GHS Balanced Nickels.
Been meaning to give the GHS a go as well.
