All that happens when someone asks this question is a barrage of answers with no reason behind them. If you like the strings you currently use (if you currently have a 4 string bass), then try and find if they make 5 string packs. That's the best advice you can get on this, IMO.

EDIT: ^Case and point.
roto swing 66, in my opinion they are the best strings in the world because they start off really bright and break into a lovely low middy tone which is perfect for 5 string i think
