I know it's a stupid question, but that is the question I had when thinking about racquet weights.
Guys if an average WTA player uses a low 11 oz racquet with lots of power and precision, doesn’t that mean that 11 oz is good enough for an average(3.5 to 4.0) male club player? An average male club player is probably weaker than your average WTA player so why not use what they use? Low 11 oz racquets.
I’m thinking there is probably a very good reason why your average female pro athlete use low 11 oz racquets. Maybe technique will suffer if you go heavy, maybe stamina, maybe swing speed and those negatives probably apply to your average male club player. What do you guys think? Maybe most of you guys use low 11 oz racquets, but I have always wondered if going 12 oz + is better. Some say go as heavy as you can handle, but WTA players who can surely handle 12 oz + racquets use 11 oz racquets.
There's an assumption that WTA use 11 oz which may or may not be correct, it would surprise me that they use higher mass as there style of play with long strokes allows for heavier racquets, where as modern ATP style relies on smaller muscles (wrist) and fast acceleration (Note: <4.5 don't use modern ATP style so shouldn't matter).
Regardless, one important point to consider regarding mass is ease of hitting. Increasing mass at the head increases both Swing Weight and Twist Weight, these two are often referred to as plow is the ability of the racquet to hit through a ball. High TW & SW allow a player to hit off centre more without losing control and power. A low level player gets the benefit of a larger and more consistent drop off from sweet spot. Also it allows for a slower swing for similar potential energy, adding a bit more control. There two reasons are key to lower level players playing better, the racquet allows the a larger degree of error giving them a much larger sweet spot and a reduce racquet head speed requirement. Personally i think if the individual is strong enough to wield a 12.3 oz (350g) they would benefit is there timing is not as good.
Another point, though contentious, a heavier racquet is harder to swing as it has more inertia therefore the player needs to compensate with more fluid stroke which although not suited to the modern ATP style is very well suited to pre-2000 style. A heavy racquet will assist in developing a longer, slower, smoother swing. The weird multi hitched swings you see more off in 3.0-3.5 will be smoothed out. Then to develop power player should start bringing in bigger muscle groups, buttocks, torso and legs, to reduce the swing length and increase acceleration.
So in summary a heavier racquet in a lower skill level can assist in mitigating timing issues and help development of a consistent stroke. So those struggling with consistency, try some lead at 3 & 9 and start grinding like Djokovic.
Note: Nadal (low Wt, low SW, low TW) v Djokovic (high Wt, high SW, high TW) v Federer (high Wt, med SW, low TW) Nadal needs hit the ball closer to the sweet spot with high RHS to achieve this he stand further back into court and swing much faster and agressively (He's the physically strongest with the lightest racquet) v Djokovic can miss hit more can swing shorter his racquet allows him to player closer to the baseline, bunt, slap and flick balls back but lacks topspin due to high ineria reducing RHS and change in direction v Federer he has mass to stand close but must hit very centred, he needs good timing but doesn't need the power of Nadal. - The point of this is that a more stable racquet like Djokovic means you don't need the ability of Federer or the physical strength of Nadal. As a armature it should allow more room for error, help get more balls into play, play deeper shots. Federer has recently changed racquet to increase TW to assist stability on his backhand. Club players need more forgiveness than these three and therefore should consider a more forgiving setup relative to their strength.
