A quick update on the heel shape and walking comfort. I have 2 SD`s, one with the 90 degree traveller, and one with the cut back cuban heel. The traveller makes the boot heavier on the swing, and quite uncomfortable to walk long distances. The Cuban heel is a delight. On the Bounty hunter, I have the block heel (traveller, 90 degree) and its less uncomfortable, perhaps because of the higher shaft giving more hold.
