I feel normal means 2% Gutta percha cones...We shall always do lateral compaction after cleaning and shaping with protaper system. To choose the right size, we should use 2%hand files and should check which file is binding at the working length. That size cone should be used as mastercone. Usually 30size cone will be a starting point in most cases
