I don't even really like regular mayo (so I would not bother making one), but I did buy the WF chipotle mayo with an order from netrition, and it is actually tasty! I used it with grilled steak on a bed of romaine. It does have a slight sweet taste, but I think the spicy is a good compliment.
I know you said you don't care for their products, but wanted to add my 2 cents for that flavor.
