Do I need to change my right hand grip to a palm grip versus a finger grip to have the right forearm inline with the shaft at address?
Absolutely not, Dave. The Right Hand Grip is a finger Grip -- as opposed to a ham-fisted palm Grip -- and the cup of the Hand (the palm) covers the Left Hand thumb. The Grip pressure should be firm with each of the encircling fingers, except with the right forefinger (with its #3 Pressure Point), which should be somewhat lighter (to keep it sensitive to the Downstroke Lag Pressure).
