Thank you guys !
I agree with what you all said about the treatment...
Alpal, what you've done is great and you example is showing some nice differences

I will talk with the guys to see what they think...
Andy, I will say the same think: interesting try !
I don't know if your results are better... I would say stronger, for sure !
The 3 of us prefer usually to be softer than stronger... and stop the curve just before the "to much" point
But, thank you for the tests; we will consider what you said !
