Hi pnearn,

You made a good observation and you are right. Actually, there is nothing wrong with an upright swing plane, it all depends on your height and build. Tall people should have a steep swing plane and shorter (and especially more stocky) people should have a flatter plane. There should be a minimum amount of tension in the arms and the best way to achieve this is to let them hang down naturally. Especially with the longer clubs, that means quite close to the body.

Cheers.
