-SOL- aren't great. Dont get me wrong, they are better than they majority of the tribes remaining on w50, and better than a lot ever were, but the days of plenty of promising tribes on w50 are long gone. The only ones i class as good are ODA and 1984. at a push, i would say hammer are ok too, but, i have no experience with any of the hammer crew, so i cant say too much about them
for where sean says -SOL- have been tested - i don't class -TOL-, FS, L0L etc as challenges. they have not been properly challenged (1984, or ODA. Heck, even Hammer are what i would consider challenges) and as soon as they are, i believe they will likely fall apart.
