May I suggest Crash that you move this topic into another area of the forum. Either into the appropriate platform section (360/PS3, etc), or in general discussion. You'll find a lot more ideas and tips there.
Your our topic is not really a Support question. Regardless, for your benefit, you'll get a lot more views elsewhere.
I like the MTar X ( whatever it's called) smg mobility with extra range (sacrificed rof).
