Swingweight vs static weight

[pico]

I would like to understand the balance between swingweight and static weight. For example, I have a Graphene XT Prestige Pro that had a Wilson Featherthin grip and 2g of lead at 12. I then switched to a leather grip today and I couldn't keep my shots in. So I took off the lead at 12 and it helped but I missed that extra penetration that the lead facilitated. How do you guys manage static weight vs swing weight?

You changed the balance by replacing with heavier grip. Add lead near the throat until you get back to old balance point. SW will go up minimally. Or you could use the MgR/i ratio. There’s a thread about this.

When you put on the leather grip you added weight to the handle which lowered the balance and increased the static weight. You also increased the grip size. When you removed the 2 g from 12 again you lowered the balance and static weight but I’m guessing your static weight is still 10 g higher than the point where you started.

One thing to consider is Recoil Weight. By adding weight to the handle you increased RW by about 6.5 points making your racket more polar. RW is the racket’s force behind the ball. Now you need to find your magic specs to start keeping the ball in. I would suggest adding weight back on near the throat of the racket but not below the balance point but above the balance point, or replacing the grip with a lighter thinner leather grip. That makes the racket less polar, higher balance, and more sluggish, but do so gradually. If I were you I would add no more than 2 g around 4:30 & 7:30 on the racket and try it. If it helps play with it a few weeks then continue adding no more than 2 g or less until you find your specs. Adding too much weight all at once can lead to arm issues. Add a little and if it helps stop adding and play with it a few weeks then repeat. I would stay away from adding weight at the butt and tip of the racket for you that just makes your racket too polar. Good luck.

EDIT: Making a racket more polar changes the balance between SW and static weight. Your racket will be lighter (and faster) with more power. Esgee48 mentioned looking into MGR/I which is a gfeat idea but you will need specialized tools to start messing around with that IMO. MGR/I is really nothing more that a ratio of mass (M) and balance (R) to inertia (I) G is gravity which is a constant.

add weight at the butt cap == increase static weight without increase in swing weight

add weight at 12 == increase swing weight as much as possible with as little static weight added as possible

in between and inside the hoop == something in between above 2 but will affect twistweight

In between first two below the throat == something in between the first two and won’t affect twistweight

All that said… understanding the toggles is obviously important, but to the other stuff you wrote about: you really need to define your problem with current set up better up front, hypothesize a solution and worry about placement only really as a means to achieve your desired goal.

Your opening sentence was tautological: 'I want to understand the balance between SW and static weight'. In most circumstances (though not always), for a given static weight, the higher the SW the more head-heavy the balance point.

But there are many things SW doesn't tell you, including air resistance. A 320SW frame that is 85sqi and 17mm beam swings a lot different to a 320SW frame that is 100sqi with 25mm beam.
