I also read an interview with Shipyard's brewer. He mentioned that they continually reuse the yeast and so it has changed over time--thus it is not exactly like the original Ringwood that he got from the Ringwood Brewery in England. Perhaps that's why Wyeast's sample is different too.
I've used 005 several times with English bitters and I like it a lot. I don't know how well it would work though, if you are looking for neutral, dry outcome. It tends to be kinda fruity and leave some sugar behind. Good for a bitter, but not necessarily for a dry stout.
I'm no expert, but maybe Nottingham or S-05 would do better for the dry stout and IPA? Whatever you choose, good luck with it. Cheers
