you need to go by what fits you , not what everyone else likes
some like more padding, some like no padding
you need to find out what width is best. Specialized has a buttometer that you sit on and it shows how wide your sit bones are. It basically a foam pad with measurements on it. maybe you could sit in the sand and then measure how far apart the dents are. If a saddle is too narrow it will feel like its cleaving you in two. if its too wide it can be hard to slide off the back. If I had to make a mistake one way or the other I would make it too wide, at least you would be sitting on your bones not your taint. I dont like the width of the silverado or devo, I like more padding so I use the PureV I believe they are silverado133mm, devo 140 and pureV 145mm wide weight wise the PureV is around 35 grams heavier
the vigo is the longest, decent width 143 a little heavy but nice padding
