Djokovic Racquets specs: weight-358g balance-32cm SW-370 Flex 60RA

Ok, got it; thank you all!
Currently experimenting with different weight rackets and curious to see what weight that the top pros play with.
In order to get a racquet to have a swingweight of 370 or higher, you need to start off with an incredibly light weight frame so that you can add the required lead at the right places.
Basically, you need a racquet that has a strung weight of no more than 280 or 290 grams. Why? Because you'll be adding around 20 grams of lead at 12:00 noon, another 10 grams at 3 and 9, and another 30 grams in the handle to counter balance. That will get you roughly a swingweight of around 370, with a static weight of 350 or less.
Nope.
You can make any frame a 370 sw. Adding at the right place? The pros at P1 don't add X g here and X g there. They vary lead placement based on what the player needs/wants.
Some players like a high sw, with maneuverability (nadal is an example). Some players like a high sw+twistweight for more power/forgiveness (djokovic, Agassi).
But saying you need an ultra light racquet to keep the frame playable is silly. Where you add lead depends totally on what you start with, and what you want the end result to be.
No, it's not silly. I can make any of my frames have a swing weight of 370 or greater, but all of them will be somewhere between 13 and 14 oz and head heavy.
My argument is if you want a swingweight of 370, and maintain 6 points HL balance and keep the static weight under 345g, you need to start off with an ultralight hairpin and at a ton of mass at the polar ends.
My own IG Prestige MP weighs almost 360 grams and has a swingweight of only 320. If I was to add another 15g to the hoop, I'd get a swing weight of 370, but it would be 1 or 2 points HH and weigh 375 g. If I was to counter balance at the handle by adding another 15 grams, bringing it back to about 4 or 5 points HL, it would weigh 390 grams, it would weigh almost 14 ounces. I'm quite sure no one in the top 10 are using 14 ounce sticks. I don't even think they're using 13 ounce sticks, for that matter.
I think you are correct, but Sampras was close to 14 oz and Gabriella Sabitini used a 14 oz racket. Daniella Huntachova also was reported to have used a 14 oz racket early in her career. I believe average strung weight on ATP is around 12.6 for top 40 players give or take a bit.
I'm sure those frames that you describe are depolarized. It's a little easier to swing a 14 oz frame if most of the mass is in the center, as opposed to the polar ends. A 370 swing weight frame that is 14 ounces is so beastly that I think even a pro would have trouble swinging consistently for 5 sets.
I agree. High sw AND high static weight(12.5oz+) is very tough to handle for most people.

I can make my frame 370 SW and keep it under 12.9 and 6pt hl.
To go from 340 sw (stock on my frames) up to 370 you need add 9 grams. roughly 332 grams starting strung weight. Add 9 up top, and add 5 under buttcap, and 5 for og. That puts you at 351 grams. Keeps balance at 5pt hl. Add another few grams under the buttcap and viola you're still under 360 grams. Add 4 grams at buttcap for 355 and you're plenty head light. The GPP by no means is a hairframe.
The real purpose of a hairpin is to dial in twistweight, not just swingweight. It's impossible to lower twistweight from a frame once it's been moulded.
Depending on the player they'll prefer the manuverability of low twistweight (rafa and his APD original have an ultra low twistweight, but high swingweight).
Some players like a high twistweight, like novak.
Oh and if you claim that it's impossible to add that much weight to the trapdoor/lower handle you don't have a clue. Last night I added roughly 23 grams to the bottom end of a client's handle. I could add more easily.
Wrong! You can also have a strung racket that weighs 340 grams and has a swingweight around 320 and add 18 grams to get the 358 gram wieght, then you can add weight in the head and butt to get the desired swunhwswing and balance.In order to get a racquet to have a swingweight of 370 or higher, you need to start off with an incredibly light weight frame so that you can add the required lead at the right places.

It is code for swingweightSwunhwswing? 'I don't know what it means...to be honest I don't think anyone knows what it means any more...scholars maintain that the translation was lost hundreds of years ago...'
