Which arm delivers the far more powerful blow in tennis forehand or backhand? Just ask Roger Federer (Tiger probably did at the open).
No contest - right arm.

In tennis many people find the single handed backhand a harder shot to master than the forehand. I mean how often do we do anything bachhanded in our daily lives? If your like me not that often. For this reason i think the backhand is harder to learn as it doesn't come so naturally. Theres also other factors involved such as the backhand is a longer stroke and requires more precise timing which is harder to execute when given little reaction time.
