Tapered strings vs tension vs oscillation

[octaedro7]

Reading a post by our fellow John Turner I learned why intonation is (or should be) better in tapered strings versus normal ones.

I've been using tapered strings for some time now, Elixirs mostly. I haven't had the opportunity of seriously test both types of strings.

That said, I've got the impression that a tapered B string feel more loose, i.e. have less tension than the regular one, and that its excursion is wider. With this I mean that the string's oscilation is bigger thus it easily hits the frets when thumbed open air.

I guess that being thiner at the point where it is supported by the saddle, and having more mass presicely towards the middle of the string (so to speak), it should vibrate more than a regular string.

This lower tension/higher oscillation thing that I describe, not only bothers because of the buzzing that occurs when thumbing the string but it also makes it harder to play technics like the double thumb, because the string bounces too much.

Does anybody have experienced this or knows better about it?

I don't have any science to support it, but my decade and more of experience has shown me that I get a better intonated, clearer, ringing tone from a tapered B, E string every time, all the time.,

Don't forget that since the taper brings the core of the string closer to the saddle, you need to raise the saddle to keep the same distance to the frets.

That can cause the fret clack too.

I may not expressed clearly enough my question.
I 've realized that you need to raise the saddle, and I've already mentioned that they are supposed to have a better intonation than regular strings.

My question is if they vibrate wider than a regular one.
So even if you compensate the distance to the frets raising the saddles, making it equal to that of non tapered strings, if they have more excursion (which is my hunch), makes them hit the frets anyway and at the same time makes them "wilder" when played using double thumb technic (they feel more loose).

So again, I have the impression that their movement is wider and their tension is lower, and that's what I'd like to confirm.

Hope is a bit clearer now.
