I'm still going back and forth with the inner foams in and out. One night I like them out, another night I like them in. I have no choice with the outer foams as I'm pretty sure there's no way to get those back in without major disassembly.
One thing that bugs me about frequency graphs is (on the Headroom graphs for instance) the 1000 HZ matching. It's typically just a blip on the radar and everything else is way different. Match another frequency and everything changes.
