I fit out a Jaguar after posting that post last night and headed back into the wormhole I found (I had a probe launcher with me this time, just incase, I spent about 45million isk on that ship).
That shot is the Alarm Clock getting pounded by a Sleeper battleship.
With that one little ship, I was able to take on 4 cruisers. I killed 2 of them and that spawned 3 more frigates and a battleship. So all at once, all on my own this time, I was taking on 6 sleeper ships, plus 2 turrets. Sure I had to warp out a couple of times just to be safe, but I had it under control.
Everywhere I look, I'm seeing people telling of how they got totally owned by Sleepers here and there. Sure, I started off in hi-sec so my spawn is an easier one, but still...
I got a lot of cool loot, and even went back for a salvage ship to hoover up all the leavings - I've started training for reverse engineering too so I can see if I can get some Phat Lewt from all the goodies I found.
I think a lot of people have fallen into the old newbie trap of "Must fly biggest badest thing possible into wormhole", my trusty Jaguar does the job brilliantly, I just need to tweak it a little more - shield booster goes on in place of the second multispec hardener (which I can't really perma-run anyway) to minimise the downtime on warpouts!
Small is beautiful.
