Hey Noodles, Check out this video from Cris at "Another Cut Above" on YouTube. I have been shaving for about 10 years with a boar brush and a couple tried and true soaps. Recently, after about that ten year time I popped back into Badger & Blade and found that synthetic brushes had really improved since I started. Having recently worn out my Semogue brush, I bought several synthetics, one of which is an AP Shave Co. 24mm synbad. I did a little cursory research to see if there is anything different about lathering with synthetics and I found this video, which has helped me to get great lather. Cris's technique is pretty systematic so you can slowly add the amount of water you need until it's time to splay the knot and whip up an impressive lather. Hope it helps.
