Shortboard/dumpster diver Explain and help

"Our board designs are direct results of team feedback, so when Dane showed up at the factory in early 2010 requesting a short wide epoxy with single concave and a huge square tail to make the summer bearable, the Dumpster Diver was born. When he came back a week later and wanted one with a narrower nose and a Rookie tail template for the Trestles contest in 3 days, the 2nd Generation Dumpster Diver was created and remained under his feet all the way through to his first final at the WCT Trestles 2009. Voted SIMA board of the year for 2010.
The Dumpster has a ton of curve in a short package, so stick to the pocket and keep it on rail."
Can someone explain this to me? How close does this board (Channel Islands Surfboards) compare with custom-shaped dumpster divers? Is it the same idea - basically a short board hidden in a fish? What exactly does "a shortboard hidden in a fish" even MEAN?
And lastly, would you recommend stock boards or custom boards in general? I don't get it - custom are cheaper?? Is that because all Al Merricks are shaped by Al Merrick, or what? I'm getting a 5'8''' custom dumpster diver - again, I was told it was like a shortboard hidden in a fish and would help me ride certain sections easier. I've only ever had a 6'7" shortboard. The guy shaper stole and ran off with it and sold it for drug money so we're starting from scratch, but that's another story. Two boards were stolen and I need to replace both. I want one to be a regular shortboard - this is the one I'm thinking of getting non-custom. I know I'm getting the other dumpster diver one either through court or through finding another shaper w/ the money I get through court. What do you guys think I should do, and if you could try to answer my disjointed post I'd greatly appreciate it. Sorry for the inconsistency of this post, I'm not well physically right now - ehhh bummer need some surf
