Bro ships with a script snort2bro but is it somewhat outdated and  
does not support some of the newer Snort options.

Thanks Robin

is there any better solution? Can i just rely on Bro policies? will that be enough? is there a real difference betwen the snort rules and Bro policies?

Well, the systems' detection approaches are quite different. Bro  
does not primarily rely on pattern matching as Snort does; its  
policies use a different abstraction. You can't really compare the  
two.
