Keep tossing bombers at the problem till it goes away.
We've been outnumbered many times, even by GB packs, most of the time never taking even a single casualty. With the ability to truly do guerilla tactics by breaking off a fight to dock out of sight on a base, resupply, and then get back into a fight our group PvP success has soared even higher then before.
edit add: A Ku Explorer is vulnerable to bombers and heavy cap fire due to being an easy target. It is a tank, though, with a massive powersupply and 7 turrets to take advantage of the power. It can still instakill snubs if your aim is good and will contribute in bringing down caps with a pulse razor loadout as long as it avoids being targetted. Against other GBs it can be a real tank that can ground and pound the smaller GBs into submission with surprising speed. It's just tricky to get in position to avoid direct fire as the enemy won't miss it......
