I understand. Reread your post and went 'ops', he already said that is not a good idea. I do make sure my ear channels are dry after doing thing kind of thing.
Which leads me to... I did what you recommended. 80% improvement already. How cool is that? We done HV. Yet another recommendation, heeded, and working.
And since this kind of post does not get consideration as such, I will state it plainly... this IS a testimonial. One of several, by me, in HV's forum.
