Thanks for coming out of the woodworks for that update, lurker.
I wish I knew what Obama's secret is. I'm pretty sure he ties a four-in-hand, but somehow either through adjusting the triangle or something he gets it so it's long, narrow, and most interestingly, concave on both sides (i.e. it curves inward on both sides of the knot, then broadens out at the bottom). I mean when I have more of a knot to work with I can adjust the width and concavity of say, a double windsor for a similar effect. But it's never as long and slender as this. His tie knots really are perfect, and no matter how much I practice I just can't replicate this with an FIH. I think the difference must be the material of the ties. The fabric must be extremely thick or something and carefully selected for the express purpose of resulting in a glorious knot. Anyway I'm not a huge fan of the man as a politician but I'm a close follower of his inimitable tie game. Looking over some of these pictures again it could be a carefully adjusted half windsor... anyway feel free to provide input.
