won a roll, what to do now?

HI, i have managed to win around 10k playing 20 and 30 rebuys. On the whole I do little if any bluffing so this money has come from good cards and good hands. I am aware my game needs aggression, as I presume this is a hot lucky patch (thank you poker gods), and also develop better knowledge of my opposition. So a general question, do you think playing the 90 player freezeouts in high volume will be a good place to practise? has anyone got any opther recommenadtions as to where to play, sites, levels, formats etc.
