Does putting lead in the throat add to the swingweight?

I'm looking to increase the swingweight of my racket, but at the same time I don't want to drastically change the balance/power/sweetspot. Would adding lead in the throat allow me to do this? I just want the racket to have better plow through but still feel the same.

SW = mr^2 if you add mass in the throat measure the distance from the butt. If your balance point is 32 cm 32-10 = r = 22 cm. If you add 2 grams I = mr^2 = .002*22*22 = 0.968 KGcm^2. This gives you very little change in power and no change in sweetspot or balance.

As mentioned above, you'd be better off adding say 2 grams at 12 o'clock and 2 grams inside the buttcap instead of 4 grams in the throat.

@MasterSlice74 , just try it in the throat and see what you think. I purchase 3 of 5 matched Volkl Quantum Tour 10s from a dude, 2 had lead in the throat and all the rackets matched in balance and weight. I hung the unweighted one on the wall, took the lead off the other 2 and play them as my main sticks at their matching lighter weight. I have experimented a lot with lead, Blue Tac and other weighting material on a whole lot of rackets, some worked others not so much. Weight and balance are individual and there is no majick, just trial and error for what feels best to the individual. Buy 1/2" golfers lead in larger quantities, you can cut it any way you want.

Adding 3g at 12 and counter balance with 3g at butt will keep the balance and add ~10kg*cm2 of SW
Adding 6g at the throat will add about 5-6kg*cm2 of SW

Im going to give you the benefit of the doubt and assume you mean the top of the handle.
No, I mean V throat.

There is not a single place to add weight that is universal to all rackets and all players.

Sometimes you add at 12, sometimes at 3-9, sometimes at 4-8, sometimes V throat, upper handle, lower handle or any combination.

From what the OP said about wanting more stability without altering balance some weight on V-throat seems reasonable to try and works well for me personally on many frames.

I have 3g on the throat of my G360+ Speed Pro. I want to say it helps. I added the lead incrementally and tried a little more before settling back to 3g.

Edit: This is in tandem with 3.2g of weight via VT Advantec strips at 10 and 2 (replaced lead there, free sample) and a leather grip. It’s been a while since modifying my stick but I’ve kept it there for months and don’t intend on changing it.

Every time I've tried adding weight to the throat, and I've done it with a handful of frames, the response off the stringbed becomes weirdly erratic.

My main thing is how much lead can you work into the throat area to make much difference? I find the top of the handle with some high density lead tape as the better way to go, with all due respect.

I can tell 1 gram difference.

On one of my RF97 I have 1g on V-throat and 1 gram on top of the handle.

On my Blade Pro 18x20 I have 3gon 4-8, 1.5g V-throat, 1g on top grip and 2g under middle of grip.

Both of these rackets have good stock swing weight, so weight was added to beef up center.

I heard adding lead to the throat can make the racket play a bit stiffer because of the depolarizing effect, I normally add lead to the throat if i want to bump the static weight but not change the balance. I like my rackets to be 6-7 pts HL.

I once was experimenting with lead which is unusual for me, but anyways i had already added some lead to 12 maybe 3-4g and wanted to counterbalance the racquet but not by placing lead to the bottom of the handle so i placed the 2-3g inside the throat and wow the change was very drastic. The racquet felt more solid or and the power increased bit time...too much that i did not like it. I'm sure if i had played with the racquet with that set up i would have adjusted to it but i was a rare experiment so i just kept the lead at 12.
