Your proportions are about right. It's a lot easier to mix the bentonite and sand in a closed contained and then slowly add water. The sand and bentonite is very dusty. It's easy to add too much water, so add a little at a time. Also let it sit overnight before doing the squeeze test. Start with a small test batch of 10 pounds or less.
To keep your sand in a useable condition, try to keep it in a closed container, so it doesn't dry out. Cats love this stuff, which is another reason to keep it closed. You may find that you have to add a litle water if your sand hasn't been used for a time.
My personal preference is for petrobond. About the only disadvantage is cost. It doesn't need to be vented. It's always ready to use and the commercially blended sand is more likely to give you better results "out of the box".
