I don't recall anyone claiming anything but softer iron in the V-Pro plates, with a harder iron, and a sort of case hardening in the sand cast. Is that right, or am I in the Twilight Zone? If I read the posts right, who's correct, Ed, or the people with contentions contrary to his? Which is it, is the V-Pro plate harder, or softer than traditional sand cast plates, and by who's authority is this determined? Also, I got into a discussion recently where (nearly) everyone and his brother claimed that the V-bar needed to be hard, *and* of a small radius profile in order to minimize string noises in the front duplex, in some cases, regardless of the counter bearing angle and length of the duplex segment. This is, again, at least partially contrary to what Ed wrote. Again, who's right, and by what authority? Also, how does a larger capo radius accelerate capo wear by not allowing the string to have a precise pivot? That doesn't make any sense to me at all and I'd like it explained. How can a longer support area for a given load, on a given footprint width, result in accelerated wear of the support? This is contrary to logic as I know it. How does this work? Let's backtrack and plug a few holes before we hotly dispute anything else, what do you say? Ron N
