From my numerous indoor basic motions this winter I've experienced, that for me the horizontal hinge is easiest done with #2 pp being the boss of the thrust, pulling the club down and through. For angled hinging it's of cause #1 pp pushing the club.

Swinging and hitting.

Rhythm and aiming point.

Since the closing part with horizontal hinging takes a little longer than for angled, you might want to play around with aiming point to get impact with the small white ball first instead of big green one.
