As was told to me- the KHG deflector is a science deflector and that I should be using the omega on my kdf/tac raptor. Now that I'm shopping for a deflector for my fed I'm looking at the AEGIS (for the shield bonus's) or maybe my mk12 Positronic I have in storage as I've never used the MACO. I use a mk12 combat [turn][spd][full] on my star cruiser with 2 mk11 (white)RCS consoles and can get near 15 turn, tho the KGH engine gives you a nice power bonus to you systems. It all depends on how badly you want to give up your set bonus's.

Have you looked at the combat-hyper engine or a fleet engine ?
