It's not about the size of your ship; it's what you do with it that counts.
If you have a wing of strong pilots
, experienced in PvP (and this genuinely is about fun, training and gaining experience) then why not plan events where the 4 more experienced players actively train the members of the other wing. E.g:
4 v 4 in original groups. Except your 4 more experienced pilots demonstrate how they can pick apart 2 'condas an FDL and a Cutter in 15 seconds without breaking a sweat. (They'll also be more likely to recognise when someone's taken enough of a beating and, thus, prevent those hefty buy-back costs. I notice lots of pilots here all willing to downgrade to much cheaper ships: my guess is that's buy-back related)
Your badass combateers fight each other 2 v 2 so you can see how they target, dodge and roll, utilising whatever ship each of them are in to the best of its abilities. Don't think an AspX is a combat-worthy ship? You gotta see CMDR Kharma with his plasmas, eg. Your more experienced pilots could be flying a variety of ships between them, demonstrating strengths and weaknesses for each ship.
2 "trainees" (for want of a better word) pair up with 2 more experienced pilots for 4 v 4 training, with rounds starting off slowly - each wing taking it in turns to practise manoeuvres and so on - and gradually getting faster and more full-on. Almost like training drills, but with space ships and beer.
Final round is back in original groups so "trainees" can put their newly practised skills to the test while being able to compare the results to the first round.
You don't need to worry about engineering, ship types, whatever. You might find people are more skilled than they realise. It's never a bad thing to give folks a chance to learn from each other. Could even find some not-asshole pvp regulars to come showcase their ships and skills, and talk pvp engineering and what have you.
