You might be interested in Fweddit. Much like you, we have tried the null bloc and we didn’t like it at all and now doing our own sort of PvP in both low and null. In Fweddit, the concentration of old farts over 35 are so much that I have called it a retirement home many times.
Even if you won’t join in the end, feel free to join our Discord and hang out with us in our public fleets!
