I make double loop flemish twists, no timber hitch's. I just add 4 pieces of B50 about 4" long to each end before I make my loop. I ened up with 12 strands of D10 and 2 strands of B50 in my loops. If you havent shot your self bows with FF strings you are really missing out in my opinion. Its amazing how much more quiet and calm the bow sounds and feels.
