MESA™ has lots of pick under your thumb,with a dimple for control, with a short picking point.
CHAPARRAL™ is the compliment of the Mesa™, not quite so much under the thumb, with a dimple for control, and a longer picking point;
PALAMINO™ is the deepest of the three picks, with four drilled holes and a dimple for control, and a long point.
And, of course, all of them can be held any way you want, and good for both right and left handed players.
