Savage is beautiful and always worth it -- I've never had a bad day there.
Beaver, MD is a good stream but very, very, very different. We've caught some very large trout in there (and seen other, far bigger fish), but generally dislike the pressure, presence of people and civilization, and fairly small stretch of fishable stream. I half wonder if people are dumping dog food in there the fish are so fat (Savage browns look skinny to me). Then again, it's close by and the Cracker Barrel in Frederick is great.
Your call -- everything should be fishing well with the temps. Take your pick!
