Moving from 1/2 to 2/4 or 3/6

[sations]

Been playing 1/2 6-max now for 2 monthes and think I am ready to move up. Up until now I have only played on Party skins. Would it be worthwhile to go to say Ultimate Bet or another site that offers 2/4 or go straight to 3/6 6-max? I have always wondered what the games are like but have never left the party skin realm. What other sites would you recommend for 2/4 6-max. Thanks
