I’m not sure how genuine you are based on your zkillboard, I mean okay you seem to roam null with gangs (I assume corp / alliance / allies) so you might want some solo pvp experience? Versus similar opponents as you desscribe. I don’t think lowsec / fw is about such things, as far as I know.
Maybe try dueling in hisec and see which people are trustworthy to duel. I see such in trade hubs sometimes (personal experience in dodixie and jita but probably most trade hubs have such, I guess, everyone sees the duel message on grid and saw plenty of such duels where people were fighting the same class of ship like frigate vs frigate or cruiser vs cruiser, just keep in mind the station games or fight at the sun), with the changes to neutral logis dueling should be even more reliable than ever.
