I don't have too many other recommendations other than the CX, or T6. The T7 will be too narrow. I'd like to try an Arbor A-frame but think that will be too narrow as well. There may be a few options from Nidecker, and then there's the more custom market as mentioned. I'd look in to Prior and Kessler in addition to Virus.
Yeah I should mention I've been thrilled with the T7 too (even though it's not available anymore and wouldn't be wide enough)... I've heard the Custom X is a great board and if it's anything like the T6/T7 I imagine it'd be great.
Another board I was seriously considering (other than the Kessler Ride or Prior Freeride you mentioned) was the Volkl Coal XT. It's a pretty serious board... I love the Virus but I don't think I would have been disappointed by the Volkl:
