You said you don't feel a difference but your wife does, and this is what I said; "As to a few ppm more or less hardness, the vast majority of both men and women will not notice a difference in the feel of their water".
I didn't say anything about me.

I got it, thanks! I set the unit down to 6lbs/cuft and my wife said something to me about it, not so much a complaint, but she noticed the water was a little different. I noticed a very mild difference myself. I would not say it was earth shattering or even problematic. If i let it go I am sure we would forget about it and be more than happy with the water, but I decided to set it back at 8lbs and leave it there. 3 bags of salt per year is not a big enough deal to bother with, I would rather my wife be happy. The "slippery" feeling is a bit different between 6lbs and 8lbs and I agree that if someone does not like it, 6lbs would be a better choice, it seemed to just cut it down a hair.
