NOS Shure V15 type III cartridge opinions

Thank for the input. Consensus seems to be that the suspension for the stylus may be suspect after all this time. I did visually inspect the cartrige and stylus with a magnifying glass and see nothing visually other than that it is pristine.  Just in case I did look for a replacement stylus and found only aftermarket stylie ranging from 13 to 88 dollars. A Phanstiel, supposedly made in switzerland, is 25 dollars and the highest priced ones are from Japan and shipped from there. Does anyone have any experience with these aftermarket stylus?
Any information would be helpful and appreciated

Aftermarket styli vary enormously in price and some are outright bad. The Japanese Jico ones have a good reputation. Shure themselves recommend their M97xE cartridge as the best replacement.
As an anecdote, I recently noticed that the audio archive of the British Library use the Shure M44 cartridge for their digitization of some old recordings, using specialty styli: https://www.youtube.com/watch?v=yI5DYJPSf-A&feature=youtu.be&t=162

The stylus is a major part of the sound character and tracking prowess of the V15. All of the aftermarket offerings will change the sound. Most are so inferior as to be ignored as an option. The only one that is consistently said to be as good or better than the OEM stylus is the Jico SAS:

There is debate as to the superiority of that one as well. Try your original. It may play fine. Listen for excessive sibilance and other signs of mistracking and go from there.

@dlcockrum 
thanks for aftermarket suggestions on t3
i have at least few chassis that need needles
i was pizzed off when I mounted an aftermarket one and quit shopping seriously 
NOS worth $arm,leg

To all that have responded,  you rock my world.  Thank you so much for your input/suggestions. 
I will try the NOS as is and if need be get the best rated albeit most costly stylus if needed. I think I'll start by obtaining another headshell first for ease of swapping out between cartridges. It's also most economical. 
Thanks again
