Update: Nope. I am a big fan of other DR strings, mainly low riders. These are just not worth it. The grounding issue renders them useless without some kind of wire harness to ground them to your body, which I have done, and it works, but is a pain in the rear. Do you want to tie and untie a wire from your wrist every time you put the bass down? I don't. The older coating from 10 years back or so did not have this issue. And even when plugged into my high end gear, I'll still get an electric pop or 2 if I don't run a wire ground, rendering tracks I record useless, I prefer to play tracks all the way thru with no punch ins. Beyond that, the tone and feel just isn't the same as the old coated strings. Frankly, these suck for passive basses that require a body contact ground. 2 stars for staying in tune like DR's always do for me, but I'm going back to low riders. Might try nickel low riders for kicks.

Original review: Hmm. I am a big fan of DR strings but I'm not digging these so far. I used to use the peacock blue coated strings many years ago, I really liked them, the coating seemed smoother and more comfortable on fretting fingers, and I don't recall the "non grounding" issue with those older strings. This coating does prevent your fingers from fully grounding the bass (the hum does get cut a little, not all the way), which is an issue on the cheaper practice amps I have around the house and studio. I haven't used it for recording yet but through my DAW interface I don't notice much hum. If I had tape wound strings that have the same issue, we will see how that works out.
I believe the older coated strings were also based on low riders, where as these are based on highbeams. Maybe I just like the feel of low riders better. Anyway, I'm surprised at how rough they feel on the fretting hand even with the coating. Not a big deal, but surprising. The sound is still bright and new after a couple weeks, so that's nice, the coating does seem to keep the strings sounding fresh longer, although I do like a more broken-in sound overall. I don't play a ton of bass so I assume if I played it more they would break-in, and as any experienced recorder knows, it's easy to dial out brightness, but it's tough to add it back in if you want to it, so this isn't really a big problem.
The jury still out for me, at this point I'm lukewarm, if I change either way I will update my review.
