I'm sadly reporting that I've too become a flashing addict.
NRG roms are just amazing. From the first flash (first days of July), I thought this was the way this phone is supposed to be. Thanks a lot!!.
I ran into trouble (although I don't use lock screen) with 23121.Sense2.5.Cookie.Jul.21 when I enabled Show Second Hand, and Enabled minute flip. I went crazy for about a day retracing my steps back until I got the guilty ones...
Running smoothly 21911.Sense2.5.Cookie.Jul.24 with no troubles except one memory problem with opera, but using cleanRam (from htc Addicts) took care of it.
Flashing now 21911.Sense2.5.Cookie.Aug.01
ssigh...
