Couldn't hold off anymore and ran the Darkslide 4.1 ROM. Decided to go with ADW's launcher with their Black Theme add on. I like it. The launcher takes a little getting used to but I'm definitely impressed, Coming from the BGX theme, it's a great replacement. They really put a lot of effort into the theme.
I'm still looking to get into some further customization, but I do like it. I had no issues backing up all of my free apps with Titanium backup then reinstalling them after the flash. Same with the market, once loaded in all the purchased stuff was just a matter of downloading again.
Very, very pleased with the speed and smoothness.
