It's been a long time since i watched these guys. Have they produced anything good in the past few years?
Black Terry has been the most consistent. He's produced truly great matches in almost every year this decade (hitting a home run against Wotan of all people) and barely fails to disappoint when needed. Stick him against any indy scrub with a beer bottle and he produces. Meanwhile Navarro is rather hit and miss depending on his opponent or setting. He's got the goods like his matches with Virus and Sabre Jr but he has some rather meandering performances. If we're all honest regarding Navarro, we tend to ignore matches that do hurt his case (mostly his contemporary IWRG work) and focus on maestro-style pairings that would/should always play to our tastes. Lucha is generally skewed in that direction, but I feel Navarro more so than say Casas.
As for Solar I don't think there's case for him at all. He's ranged from average to downright bad at points (the latter mostly when tagging with his son). Along with the Navarro/Solar touring act becoming stale a few years back, I don't think he has much to bring anymore. Much like Pirata Morgan, he should probably put his career to pasture.
