Are copper pipes more effective than the standard contacts?

I have no data to substantiate which is better. As long as the contact material can provide sufficient electrical conductivity, I cannot see why one would be better than the other.

There are others who have expressed concerns, that choice of material used for contact rods can influence whether the material is absorbed into the body. The surgical grade stainless steel rods supplied by Spooky2 should not adversely affect an individual. Copper certainly has benefits documented of its own regarding use in other modalities, but one has to be careful not to absorb too much copper and have it go out of balance with ones zinc levels. I again stress I have no data as to whether copper rods used in contact mode even results in copper absorption, and certainly there are many who do in fact use copper rods.
