Yes mate 11ltr pot's are about right for there final pot's aslong as you have the height/room in your grow space because the bigger the pot's the bigger the plants will finish.
Another good thing to remember is after you repotted them into there final pot's always give them a week or two more veg before going 12/12 (flower) and this gives the plants time to get over any stress after the repot and also gives the roots time to root into the new soil.
