Buy T-I flats or other T-I's; Dean Markley blue steels are a fairly elastic musically bright string - the sound may take some time getting used to in my opinion but worth it for rock; DR's are elastic but offensively bright in the hi-beams-much easier for me to like the lo-riders but still didn't like the sound & switched to T-I jazz flats; Rotosound makes some of the best sounding flat strings ever but are high tension - even the monel flatwounds; Ernie Ball good strings medium tension nothing really stands out about them IMHO but nothing objectionable either; the same opinions i have of the Ernie Ball Flats I have of the D'A XL nickel roundwounds. i'd like to checkout D'A tapewounds in the future. years ago I would simply buy for fretted basses whatever was on sale. TI flats are my general string of choice - especially, on my fretless warwick. these strings sound more like an upright bass than any other string i've tried.
Which of this sets have less tension?
