Oversized Frame vs Isometric Frame - Pros & Cons

[shinn]

anyone can tell me the pros and cons of a normal head (isometric) vs an oversized head??

[Sketchy]

Over-sized rackets:
+ Larger sweetspot, so more forgiving of off-centre hits (may also generate more power for any given swing speed, due to the longer strings).
- Greater aerodynamic drag, so swings much slower (a player with good technique will generate more power from an iso or oval frame).

Essentially, they're good for beginners/intermediates or more defensive type players.
Oval frames are pretty much the exact opposite - less drag than iso frames, but more forgiving.

oversize head also has slower response. you will need to string it tighter to get the same speed out of the strings.
