9BB/100 at 25NL is fine. If you want to start rasing more then raise some hands situationally and start blind stealing more. Stuff like that. In full ring where they are going to pay you off anyway though you really dont need to be raising many hands before the flop IMO. Some stuff needs to be isolated but all the 86s, nut sort of hands that you want to play are best just limped if they are going to pay you off anyway.
