While as 3835 says, these are niche balls, my Slate Blue was so strong and early, I couldn't use it as a dry lanes ball, nor even as a light oil ball. It was earlier and stronger overall than my Avalanche Urethane Pearl which is very suitable as a dry lane and light oil ball.
Meanwhile, if you find the right Visionary aficionado who knows what this ball offers, I think it is still worth a decent amount, minimum $95 - $100, maybe more. With the right drilling and on the right surface, the ball hit more like a resin ball.
