Feature:
I don't find any useless features in these strings! This unique guaging is perfect for me because for a long time I wanted a guage that was in-between 40-95s, and 45-95s. The taper winding makes the sound much more alive and gives you much clearer sustain.

Quality:
Quality is superb. I have never gotten a defective set of these. For the tones I generally use the most, I need the strings to sound like they are brand new. These keep hat sound the longest, which is about three months for me.

Value:
Definiteley. I would recomend these for any level of bass players out there. A lot of musicians don't realize how much strings affect how you play and sound, regardless of the instrument.

Desirability:
I personally don't think that a string or an instrument for that matter has "sex appeal". I mean this is an instrument, not a bikini, but I don't think that a bikini has any sex appeal either. I do think these strings are desireable for a ReFined sound.

Sound:
These strings are Amazing! I cover alot of styles in my playing, so it's important that the strings has good feel, tension, and tone. I get a bright clear tone with more midrange, deep, boomy bottom-end, super slap tones, and rich harmonics.

Ease of Use:
Very easy. I set my amps to what I need, and make all the changes from the bass itself. I even found that these strings sound great on my fretless bass. Jaco did use round wound strings, which alot of people don't know. So if you really want a more "Jaco" sound out of your fretless, use these. THese might be even better than the rough Rotosounds that Jaco used.

Support:
I have never had to contact Dean Markley for bad quality control.

Overall:
Definately for a long,long time. Maybe someday I will contact Dean Markley to tell them the make a stainless-steel version of these!
