I'd agree with the Viper 3 recommendation it's a fine combat ship small, fast, decent agility and firepower, also as mentioned tactics play a large part of BH especially at entry level for example leave wings alone as they can cause trouble for larger more powerful ships simply because you;re going to engage them one at a time.
Keep away from HazRES and compromised nav beacons as the "pigs" are your friends, always wait for the scan to finish before firing, know when to run (it's usually before you think you should!), always remember it's not just the rebuy it's the loss of hard earned bounties so cash them in before your luck runs out.
I use a Viper 3 for CZ as it doesn't have the enemy ganging up on you like a larger more powerful ship and it's small, fast, cheap, expendable....... engineered it's even better!
