I finally flew through the lapping tail of a neutron star jet, and wow, it was scary (especially with months of data on my ship). With 7 or 8 months of exploration data, would it be foolish for me to experiment with neutron star jets? What about the neutron stars with the stronger more violent jets (I believe they're called pulsars)?
They're safe as long as you pay attention and are prepared, never let your fsd go below 80% and only supercharge on the very end of the jets and they are safe
Even if you get stuck in the jets ( you shouldn't) you can escape despite what ppl are saying, just high wake to another system then you don't need an escape vector just point your ship in the general direction
If you have never tried it and are risk adverse then wait till you have cashed it in, I use the neutrons to travel on long expeditions, only 3 weeks so not quite the same scale but I've covered some 50kly and I'm still jumping using them, but then I've had plenty of practice and am confident I can escape the jets even if I get stuck in the jets by doing something stupid.
if your jumping between neutrons where they are quite dense - 1m15s from one neutron to the next I've got it down to and that makes some fast travelling indeed ( get your calcs out

)
On the flip side I avoid white dwarfs they're just not worth it and their exclusions zones can be ridiculously large
Ultimately though ask yourself how annoyed you would be if you died then decide to use them

my fist play with them I had a few close encounters I didn't die though, but I did learn to survive them
