Mike I believe you are correct but isn't that simply a side effect? Leech tension and sail twist should be controlled by the mail sheet and vang. In fact I think the opening of the leech is experienced more with changes in backstay tension as a result of changing the position of the masthead.
Correct me if I'm wrong but I think that your statement is metaphorically equivalent to saying, "The backstay controls main sheet tension." True the backstay can affect main sheet tension, but that's not its purpose. Likewise, bending the mast can open the leech but that's not its purpose and the components designed to control the leech (vang and mainsheet) are still available to "close" it. Kind of a does the tail wag the dog situation.

Cunningham does flatten the sail but simply due to luff tension. If a baby stay is able to pull the belly of the mast forward then the luff is also pulled forward and the resulting shape of the sail is flatter.

Both depower the main.... Does the adjustable baby stay (mast bend) make the Cunningham (luff tension) redundant? I have an adjustable baby stay, is adding a Cunningham a waste of time?
