Perhaps one is a better match for your arm than the other? A bit of LF resonance could easily account for a slight reduction in tracking ability which in turn might cause sibilance....
If you have a USB microscope - looking at the needle is possible too
Just a couple of thoughts
bye for now
ld wrote:Hi CL. You'll probably find a USB microscope doesn't cut it to see the nitty gritty bit that matters, only good for gross-outs I found. I'd suggest looking out for a lab mono optical which have fallen out of fashion and are pretty cheap. They can actually let you see the detail you're interested in, which is still right on the limit and largely determined by optical quality, which pastes the USB scopes IME. Easy enough to fit a normal digital cam for captures too.
In any event, I'd love to see good images of the various Jicos.

Generally they come with a range of eyepieces, and some means of getting to about x600 or x800 is in order really. Remember it's typically easy to lash a normal digital camera to the eyepiece, which can provide a bit more mag, but the detail of what is trying to see is near the limit of what can reasonable be obtained optically. Nevertheless it can be good enough IME. The quality of optics ultimately defines what detail one can see, even at relatively low mags the eyepiece/camera can always zoom.

BTW, even if tip profile isn't the shibata, that's no reason for it to mistrack/be sibilent. It's possible to achieve excellent results in that respect even from spherical styli, it has more to do with the whole bundle of stlus/cantilever/suspension/armature than the tip IME. I suspect something has gone wrong in this case, and even with a loupe you might be able to see a gross-out......?

Would the facility to adjust polarisation make it easier to view facets of the stylus?
