Anybody out there re-cantilever their cartridge with a Soundsmith Contact Line diamond ?

The question is : what are the sources of one's information?
My, say, theoretical source, is the information we got from
J. Carr, according to whom the least intrusive is stylus only
change. Nobody ever mentioned damper (''rubber ring'') change
while we have no idea about ditto suppliers . From my friend
Axel Schurholz I know first that changing the stylus only is much
more difficult than cantilever/stylus combo as provided by the
suppliers. But the price difference is about 200 versus 500 euro.
So, obviously, the retippers will prefer the combo. 
Then not all styli shapes are available to all retippers. This means
reduction of choice, I wrote to Japanese ''jewel'' companies 
for Axel who accepted too many orders but never got answers
from them. So the styli choices were reduced to boron/nude
Shibata or aluminum /elliptical. The problem by stylus only retip
was according to Axel the right dimensions for an particular sample.
BTW he refused to do ''stylus only'' repair so I moved to ''Expert
stylus. UK''. This company produce their own stylus called 
''Paratrace'' which looks like micro ridge. This work is done by their
their chef engineer with 40 years experience.
Depending from  one's perception of the involved costs and own
means one will chose accordingly. I seem to be more pragmatic in
 this sense than my Slavic brother chakster. Despite the fact that 
I can afford more expansive solution I will always choose for stylus only solution. 

Dear chakster, I know that you are very fond of those '''hollow''
boron tubes or cantilevers. But how many do you like? As you can
see on your own picture there is one extra tube on your ZYX in
which the stylus is glued. What one does not see is the extra
aluminum ''tube'' on which the coils are fastened and in which
the cantilever/stylus combo is glued. The so called ''join pipe''.
When I posted my sample to Axel he installed an new boron
cantilever and his ''nude Shibata'' instead of this ''remarkable''
ZYX cantilever. Why do you think that this way of installing the
stylus is better than usual? Or, to put this otherwise, why is one
extra tube necessary? When this stylus is wear off the new
stylus can't be glued instead. So the whole new cantilever/stylus
combo will be needed which is much more expensive than stylus
only exchange. Or so I think because of my own experience. 
BTW what I admire in Axel's work is his persistence to do his
job. As I wrote in my ''irreparable carts'' thread those glued 
together plastic bodies have no ''entrance'' possibility to their 
inside parts. How then should an ''retipper'' fix, say, the damping
 or the coils of such cart? Axel cut and drilled the body to get
inside. I don't believe other retipper will even try to do this.
BTW he was not able to fix this way my Sony XL 88 D. 
This Sony was of the same ''plastic glued together body''.
