Obviously, I'm sure more experienced eyes (such as yourself) will probably see a lot that I don't, but here goes:
I see a "pop-out" type takeaway that takes the clubhead at least slightly inside the hands (Garrigus more inside the hands than Toms), that then gets lifted to the top to an almost across the line position. Then a slight "mini-carry" as the downswing starts. Hips open a lot on the way down, with a little down-arch into impact. Clubhead goes left quickly after contact, with the shaft exiting "lower" through the shoulders. Also, lots of side bend into impact, with retained right arm/wrist bend, and a late "line-up" and flattening right wrist.
More of a general pattern similarity, a la NHA.
