When looking at the differences between an arco and a pizz string are the main differences going to be in sound, or are they going to be in their ability to be bowed or feel plucked? I have read about differences regarding sustain between the two. This question is more of a generalization between the two classifications of strings and I know what each brand will be different and perform different than another. That being said, is it that pizz strings sound not the best when they are bowed (too bright)(too scratchy, weak or thin sounding), or is it more that they do not do the job as well..ie physically harder to bow, such as the bow doesn't grip as well, need more rosin, more pressure from the bow on the string etc... I am sorry if this has been asked/answered before, but I could not find what I was looking for in a search.
