I have recently purchased my first Simpson brush, Commodore X2 in best, which was quickly followed by my next, "57" in best. I love the X2 as it is almost perfect for my needs as well as the 57. My problem is that I am ready to buy yet another one and I am looking for one that is basically a marriage of the two. Size of the X2 or a touch smaller as I plan to use this one more with my travel kit, with the feel of the 57. I have compared the different sizes and practically all the brushes but I am looking for some direction from "the masters of the badger" on this forum. Any ideas?? Perhaps a 55 or 56 or an X1? How did I get on this slippery slope?
