IMHO, BBSP is right up your alley for the type of riding it appears you enjoy. There's some great stuff to go explore off trail as well (cabins, mines,etc). The lajitas trail loop is cool and has a little flow mixed in for good measure. The last bit is pure desert tech. We did it around christmas and depending on the wind, we were usually in short sleeves. There's a bunch of cool stuff to see up on the basin as well but its all on foot.
