I bought on 10 April 2013 and it is one month and a half that I have mounted on my 6 strings patitucci.
for now, I think they hold up well it ...
That said, I do not think they have marked as ernie ball or rotosound personality.
the advantage of these strings is that the thread is less important on the length based on the bridge saddles, roughly the thickness is almost equal to the depth where the rope rests on the bridges, which, according to the luthier who set me my bass, provides better stability and prevents the rope out of the saddle (you never know, she might want to go out into the open air stretch legs?).
apart from the fact that here makes slap Well, I do not find to fall backwards, but it may be a good thing after all ...
issue price / quality ratio is good!
again to choose? I do not know .... there are so many brands of strings that I want to try and I'm not going to deny it! ah! ah!
