I've been using DR Nickel Lo Riders on my Jazz and love the way they sound, feel, etc. However, I've found that they're a bit looser than I'd prefer for most styles of playing (especially since I often tune down a half step). The .045-.105 set I use is the heaviest one they make for 4 string, as far as I'm aware. Are there any strings that come close to their sound and feel with a little bit higher tension?
. In that case, I've found D'Addario XL's to be slightly stiffer than Lo's, with GHS Boomers being considerably stiffer and something like Rotosound nickels being stiffer yet.
