I've tried Westsoy and it's OK, but Soy Slender is my favorite. It has 5g carbs with 4 of them being fiber plus it's so good I can drink it straight out the cartoon...and I normally don't like the taste of soymilk. I'd buy Westsoy if it was on sale, though since its good for milkshakes and smoothies. Use soymilk instead of reg milk in the milkshake recipe...you won't even taste a difference and its' healthier IMO.
