PakDa, one issue you need to consider is the person the blade is being purchased for. One person will be fine with a heavier blade. Another person will have their stroke speed slowed down enough so that this impacts their ability to create the strokes.
If the person is physically fit and able to keep a high speed on their offensive strokes, then heavier weight will have more solid feel, should provide cleaner feedback, should have a better feeling (less unwanted vibrations, more of the vibrations that help you feel the ball better). And the heavier blade will feel a little faster. But there is a point of no return. For each of us, at some weight, the weight of the blade will start to slow down our acceleration and our top speed in stroke mechanics.
88 grams seems like a good weight to me. I like 91-95 gram blades for me. But 88 is fine.
83 grams would be good for someone lighter, not as strong, less physically fit, or younger.
But this is also personal choice. I know people who, the way they use their strokes has much more to do with racket speed and when you have someone like that, a lighter blade will give you a faster racket speed. Someone also mentioned recovery time. A lighter racket makes it easier to recover faster.
Many of the top pros use blades that weigh someone in the ballpark of 88-96 grams. Here too, it really depends on the particular pro.
Important details to note about information presented above: the reason blades differ in weight is because wood was once a living thing. I have seen Viscaria blades that were as light as 78 grams. I have seen Viscaria blades that were as heavy as 98 grams. The blades were the same size. The plies were the same thickness. Otherwise they would not be the same blades. But the wood is not exactly a fixed commodity. Is it the density of the wood that changes? Is there more resin in one piece of wood? More moisture? It really depends. But my experience is, if we are talking about two of the same model blade then the only thing different should actually be the wood when it comes to the weight of the blade.
And the denser more solid woods (from whatever cause) usually cause the blade to feel better AS LONG AS the weight does not compromise your stroke mechanics.
If you have two blades that are the same model and one has a notably bigger head size, or handle size, or blade shape then they may not actually be the same model.
Stiga has done things over time, like older models of the Clipper are 6.4mm thick and now the standard is 7mm thick. None of them are exact so slight variations in thickness could occur. But, usually a blade maker does something to note that something has changed. Also, at one point they used to make the Clipper with 9 plies. I would not consider a 9 ply Clipper, a 6.4mm thick Clipper and the current standard 7mm thick 7 ply Clipper to be the same models. Something was changed in each of those changes to the model.
But you still can have a wide range of variations in blade weight when the models are functionally exactly the same.
In the end, the most important factor in deciding what will be right for you would be to take into consideration the person who is using the blade and how they play. Without that, it is kind of hard to determine if the better feel and higher inertia which causes higher speed will be the right choice for the person or if they would be better off with something not as heavy.
