Ah, interesting that they'd print the strung specs on the racquet. Thanks. And thanks for your comment about the quality of the racquet--that makes me even more interested in trying it out.
BTW, any idea why the Dunlop AG100 and 330X both weigh 11.7 ounces, and the AG100 is less head-light (7 points) than the 330X (9 points), but the AG100 has a lower swingweight (312) than the 330X (322)? I'm confused. Or is it just a tolerances discrepancy or manufacturer's variance during measurement?

Hmm...I'm not sure how that could be in this case, though. If I have 27"-long objects, one of which has its weight concentrated near the handle (vertex) end, and one of which has its weight concentrated near the head (apex) end, both of which have exactly the same static mass...then shouldn't the one whose mass is distributed farther from the vertex (i.e. the AG100, with its relatively head-heavy balance compared to the 330X) have a higher swingweight, by definition?
Unless I'm completely misunderstanding the swingweight concept...quite possible!

If there is more mass near the balance point,, then the swingweight will be higher, the balance unchanged and the weight unchanged. That is likely what is happening here.
Even if the balance point is closer to the handle on one, any added mass near or at that balance point is going to drastically increase the swingweight as the swingweight is measured from just in front of the butt cap.
Therefore, you can have two sticks that weight the same, with one being more headlight, yet still having a higher swingweight as it has more mass at the balance point (further from the handle compared to the other one).

Chris, thanks for the attempted clarification. I'm still not sure I understand that, though. I must be totally dense not to get this.
I think I see where you're trying to go with the explanation, but I'm not sure it makes sense to me unless the two sticks being compared had identical balance points to start with (which isn't the case with the AG100 and 330X). You said this: "Therefore, you can have two sticks that weight the same, with one being more headlight, yet still having a higher swingweight as it has more mass at the balance point (further from the handle compared to the other one)."
But if stick A and B weigh the same, and stick A is more headlight than stick B, then isn't stick A's weight concentrated CLOSER to the handle, by definition? Otherwise how can it be more headlight than stick B? So the balance point would be CLOSER to the handle than stick B's balance point. Thus, if the weight of stick A is concentrated mostly around its balance point, that's still closer to the butt-cap vertex used to measure swingweight; while stick B's weight, even though maybe it isn't concentrated at the balance point itself, is still generally distributed further from the handle, and thus should still be a higher swingweight?
I think I need a graphic or something
