D'Addario beta test

i just put on a set of new D'Addario trebles that are still in beta test phase. The gages seem consistent with the pro arte normal tension, but they feel lighter. Let's see how they work. I'll post an update soon.

Update1: I've gone through three sets. There first one felt very much like the usual Pro Arte trebles to me. Pretty good. The second set was white nylon, and sounded very good, with great sustain and good tone./ The third set is black nylon. I'm a bit frustrated with the tuning on this one, so the jury is still out.

Update: the third set turned out pretty bad. different parts of the third string could not agree on at what frequency they were vibrating...
