This is in regards to Furballs post. You guys said it is ok to go for a while with a full system w/ no pc3, but how long is it o.k. to do this. If I go ahead and get a full system it will be a month or two before I can get the pc3. Is that o.k to do with no adverse affects? I will do the pair removal when I put on the full system. Thanks for the help. Chris
