Why the huge swingweight difference between these two?

Is it the difference of 6 grams?

My iPrestige mid weighs 360 grams strung, PC 363 grams strung but with leather grips.

As an extreme example, imagine two racquets of equal weight and length, one with most of its weight at the midpoint and one with that amount of weight divided between the butt end and the top of the head. Both thus have even balance but very different weight distribution, and different behavior when swung. Thus, the specs we commonly look at don't tell the whole story.

Yes, that's probably the case. But could you tell which racquet has higher swingweight, the one with most of the weight at the midpoint or the other one?

I have two PS 90, and i have matched them (weight and balance), but there are still remarkable differencies in feel. That's why I'm interrested in this.

Actually, I find that the IPrestige is better balanced. With the LM Prestige Mid, there is a bit too much weight towards the handle and too much weight overall.
