After much too-ing and fro-ing, I'm pretty sure my next tour will start from Berlin (end of April). We've been looking at what cycle routes are on offer, and there seem a lot. We're toying with the idea of heading out West, through Potsdam, but are unsure of what routes there are aound there. We've seen that the Euroroute 1 kind of loops down around there, and there's the Elbe to go back up on, but we'd be interested in knowing what the land is like around there.
Our other options are to go up towards Penemunde, or south to Dresden.
Anyone got any opinions either way about what's god and bad, or how worthwhile the country west of Berlin is.

Anyone know what the country East of Berlin is like, for that matter?

Thanks in advance.
