Why sould i glue those Pure badgers ?

[Doryferon]

A friend of mine gave me 2 pure badger knots
Base knot 24mm and Loft at 67mm,he get them from PC Woodcrafts and Pens.
If you remember my previous "how i test my knots" you can understand better the procedure:

Here they are out of the box:





I wash them,let them dry,i load a soap and i made palm lather
I rinse them,let the dry,here how they look like:





I took each one as is dry and made some swirling movements in my palm
No hard push just simple moves as i do in my face lather
It's not a torture,few times left to right and right to left as a normal shaving,here the results:




For me that's a knot failure,no good backbone,not adequate for a proper shaving with swirling movements,just painting that i don't like it !


In comparison with a Frank Shaving pure badger knot,24mmm knot base glued few mm inside the handle.
Here they are before the test,both of 3 of them:



Here they are after the test,take a look the FS's,almost as it was,stiff and ready for more action
The PC WP's they just collapsed !



How can i make the decision to glue those knots ?
Would any of you take the risk and glue those knots ?
Tell me your opinion.
