737 NG Idle Sound?

Hello,I was just wondering whether anyone knew of, or had a 737 NG idle sound recorded from either the cockpit or the cabin in front of the engine which I could use for a soundset, or if not, a video which has it? I managed to record many sounds from recent 737-800 flights I have been on, but the idle sound I have managed to obtain has a lot of talkin in it which cannot be edited around. I'm asking this as I'm in the process of creating an accurate 737 NG CFM soundset for use with FS9 and the idle sound is the only thing which I am requiring.CheersTim
