An alternate technique (especially when vertical fishing brush) is to use a drop shot. It'd be a bigger weight on the very bottom and one (or two?) of your same hooks tied a foot above the weight. (Your second hook, if you so choose, would go a foot above the first.) A half ounce or better weight on the bottom will keep the line taut and you'll feel even the lightest bites. Also, you won't get hung up on the brush.
