In the last week i have changed the x's only twice with no problems.I am not trying to brag,i am just again making the point that for something you should never do, i sure havent had any problems.
The reason i did it that quickly is i am experimenting with different x's,i know what mains i want.This is just another benefit of this method.You can try different x's without changing mains!
