I've not yet tried the EB Cobalt flats, but I'm a fan of Jameson Labella's and I've been using them for years. I currently have them on two precisions and a jazz... and numerous others in the past. I've never needed to cut the nut, they fit just fine. I love the sound of TI Jazz flats but swapping between basses/strings and the differences in tension is disconcerting. When you get used to the extra tension of the Labellas, 'normal' strings start to seem a bit too floppy. The stiffness allows me to get the action a shade lower than I would with your average rounds, which means less pressure needed to fret, so for me these things even themselves out. They last for decades, sound great and mellow with age. I'd say try a set. You see used sets for sale occasionally on this forum. I don't understand "too much tension to set them in standard?", you might want to adjust the relief in the neck to suit, but you might want to do that for another brand of string. Good luck.

You might do better to start a thread somewhere than use status updates.
