If he has a wing that works for him why is it a mistake or inappropriate? Because it's not what you are trying to sell?
That's really not the case. I sell nothing, and I'm equally disinclined to answer such a question for the same reasons Tobin stated. The hypothetical is just not the way I would like to dive, so I would choose not to do the dive. If you feel differently, certainly let us know what you would pick and why.
