@Goosyphus - if it helps to justify, I will say these and the RW Pecos are very different in nearly every aspect. I too have the pecos, and I had the wesco samples in the smooth out, full height version of these and can attest to how different they truly are.
The wesco have a round toe, while the pecos has a more classic roper toe. the color of the two is also vastly different. The wesco is more of a light tan while the pecos are almost orange. Also, the sole and heel is really what sets the two apart - the wesco has the double mid sole and the higher heel, which works much better for jeans with lager leg openings and thicker cuffs. While the RW looks fine with straight tapered bottoms, the wesco will look fantastic with straight and slim straight models as well as the slims due to the shorter shaft.
I like my pecos, but these would easily overshadow them in very way possible.
