I put a bottle jack under the leaf spring bracket also. I'm concerned of the fact that by running one tire up on blocks to raise the other, the weight load on that tire and axle-end is doubled, stressing the tire and axle from being way over capacity. Using a bottle jack (or jacking up the frame), you don't have that problem.
