I've said this recently. I use IO. Check out what most if not all of the moderators for this forum use. There are more expensive salts that say a lot of things about how good they are. IO is tried and true. Don't bother switching in my opinion. There is no real benefit and if some believe that there is, I doubt that they can scientifically prove that it was strickly a result of switching salts. Once again, just my opinion.
