Upwind, no matter how much tension I put on it (as shown: 4:1, now rigged as 8:1), there is no change.
Absolutely needed (for your configuration, which is close to mine).
As soon as you ease off below a close reach, the vang is going to control the leach tension. On the wind, the leach tension is the mainsheet's job.
