I know you have experience
I just wanted to be sure you tried everything
My opinion on the ROM is that it runs pretty well. It's already smoother than HC ROM and on par with the latest A500 leaks. I had a crash of the 3g component while I was searching for a network but it came back to normal quickly.
3G network is strong and goes up to HSDPA as it should. No disconnection an download speeds are as good as you can expect.
WiFi works fine too, I let the market download about 20 apps in a row.
Speed is fine, could be better as there are a few minor slowdowns. No crash for now.
