Its just 5sq in difference so not a lot and I think TC95 is more like a 96. If you examine them closely with the heads on top of each other you’ll see 100 tiny bit wider and a bit more space in lower head like Carreau said. You'd certainly feel it in play.Am I missing something - the head sizes looks almost identical
Damn those look awsome [emoji2956]Did my homework this morning:
https://www.dropbox.com/s/fryh6w3klvoioez/IMG_1527.jpeg?dl=0
Some data:
Angell reported specs:
319,8g/305mm/292SW
319g/305mm/292SW
Actual measured specs (naked):
White: 319,8g/304mm
Black: 318,7g/304mm
White stick + strings: 334,6g (strings SPPP1,18/Co-Focus1,18 = 14,8g)
White stick + strings + OG + dampener (full ready): 341,7g/31mm/322SW/20,80MgR/I
Black stick + strings: 335,3g (strings itself: BlackCode1,24 = 16,6g)
Black stick + strings + OG + dampener (full ready): 342,6g/31,2mm/326SW/20,75MgR/I
SW measured with SwingTool.
And I'm quite tall guy, so, MgR/I shall be okay for me.
What is the function between mgr and player height?And I'm quite tall guy, so, MgR/I shall be okay for me.
In theory, 21 is ideal for average height, less than 21 for tall and those who wear wristbands, more than 21 is good for shorter guys.What is the function between mgr and player height?
Did you see the video on the Angell Facebook page where adding 1 gram at 12 added 6 SW points?
How do you even calculate this? Is there calculator anwhere or at least a formula?In theory, 21 is ideal for average height, less than 21 for tall and those who wear wristbands, more than 21 is good for shorter guys.
Is there a video available showing this fact?That has been discussed a bit here. Fact is 1gr at 12 is always 3sw points. Just used an rdc on Friday and measured 3sw points for TW Tungsten tape at noon.

worst case scenario, play with what feels good. dont look at the numbersGuys, Im thoroughly confused so please help me out. On paper 1 gram at 12 o clock should not be more than 3.3 points in swingweight. See TWU calculation sheet. I was wrestling with that for a while this morning. But then, I just saw Angell Facebook video and it shows 1 gram at 12 o clock increasing swingweight by 6 points. Every customizer who I have spoken to says it is roughly 3 points for every gram at 12 o clock, and no way can it be 6 points and that their machine needs recalibrating. I don't have access to rdc or swing weight calculating machines. Can someone pls clarify further? Many thanks.
Yeah I am old school and I already play by feel. I just want to know the accurate numbers for my own record and knowledge.worst case scenario, play with what feels good. dont look at the numbers
My TC100+ has 353g, 32.1 cm balance and 347 SW.There is a magic Excel. You can write here your weight, balance and swing weight - I'll calculate it for you.
Unfortunately you'll need to use an RDC machine. Not the answer you're looking for but that's what will give the most accurate numbers.Yeah I am old school and I already play by feel. I just want to know the accurate numbers for my own record and knowledge.
Most conventional wisdom out there is 1gm @12 adds 3-3.5 pts to SW. However Paul’s experiment is compelling IMO and leaves perhaps some questions on his machine needing calibration which I highly doubt. He is not some amateur, he is an engineer and with more knowledge than all of us put together on how to customize a racquet. So for me that leaves the window open that conventional wisdom isn’t a rule. There are individual influences in different racquets that may effect SW differently for the same given weight. For instance, a less HL balance will effect SW more or an already higher SW will effect any addition with more exaggeration so it’s not just a linear relationship. Also, most people apply lead tape which will be a bit more spread out when applied and not completely concentrated at exactly 12 as the weight used in the video experiment. In short, RDC will tell you after you applied your tape.Yeah I am old school and I already play by feel. I just want to know the accurate numbers for my own record and knowledge.
No doubt. I agree with your assessment that it could be a variety of factors perhaps? However, I should also mention that my TC97 16x19 showed an increase of 3 points when I added 1 gram of lead tape at 12. I saw it with my own eyes. Swing weight was 320 and ended up 323. Pro shop I was at was using Babolat RDC machine. This was over a year ago. Wish I had my phone on me I would have made a small video clip. I'm sure someone can make a video clip, I'm definitely not the only one with that experience.Most conventional wisdom out there is 1gm @12 adds 3-3.5 pts to SW.

Simple math for inertia (SW) the mass times the distance squared is the inertia. Inertia is additive so no matter what the inertia was before you add weight the SW (assuming you're using a 10 cm SW axis) will be 57*57*0.001 3.249 KgCM^2 for every g of weight at at inside the head @ 67 cm from the but or 57 cm from the 10 cm axis. I'm not sure what Paul's experiment was or what machine he was using but most inertia machines measure in whole number so if 1 g is added to a racket at 12 o'clock and the SW is rounded off to the nearest whole number the increase could be 3-4 points. I've also seen an RDC machine that did not give the same identical SW every time the racket is tested either without dismounting the racket or making any changes.

Only if the point where you add the weight is ~77.5 cm above the SW axis or you're using inaccurate measuring devices. I would check the weight twice and the SW at least 3 times to see if your measurements are accurate. It only takes a minute.somebody said:Whilst swing weight of a racket is important, it's also important to understand the changes that can be made by just 1g of added weight. Adding 1g of weight to the tip of a racket will be almost unnoticeable on court, but will give a swing weight reading of 6 points higher
Thanks for your informative replies, Irvin. What do you think about the video that @topspn above posted? Do you think the swing weight machine is faulty?Only if the point where you add the weight is ~77.5 cm above the SW axis or you're using inaccurate measuring devices.

Not necessarily faulty I mean I’m sure it is in the ballpark. I bet it he added 5 g it would not go up 30 points. Those machines measure SW by timing the period, if the period is off by 0.001 sec which is not much your SW changes by probably a couple of point. You can prove that with the TWU SW calculator. That calculator uses a time for 10 swings put in a time of 13.01 for 10 swings and 13.00 for 10 swing and watch what happens to your SW keeping the weight and balance exactly the same.Thanks for your informative replies, Irvin.

Ask Paul who is correct here @Racketdesign. If that increase of 6 points is accurate you’ve proven work that Newton did 300 years ago wrong.The video is by Paul Angell who as you may know is an engineer and racquet designer so it is not my video.
I don’t have a horse in this race. I simply offered a different explanation on the conventional wisdom of 3-3.5pts per 1gm @12 vs what the video showed.

I don’t have a horse in the race either. If there is a way that a 1 g weight can change the SW on a tennis racket by 6 points though i’d Love to see the logic behind it.

So just so I understand, i had suggested that perhaps their are influences at play and it is not a rule that 1gm @12 increase SW by 3 or so points. Meaning if maybe the balance is different it will exaggerate or diminish the effect of the 1gm weight. Or if perhaps the SW is already high then added 1gm will have a bigger effect ( so the effect is not linear in nature). So you’re saying math does not support that?I don’t have a horse in the race either.

I have used an RDC and added 1/2 g to the butt once and watched the SW go down. I thought it was possible to lower inertia by adding mass as a result of that test but now I know that it is impossible.
They have a demo package for first-time customers. All string sets 40% off. I ordered gauge 17.

What’s your main racquet @Subaruvich? Really love BK 1.28 on my TC95s
Don’t use the strike force in a full bed. A smooth poly cross will help it play better.
Thanks...so...how could I get closer to 21 number? Is it even necessary? I'm 189cm and I allways play with wristbands on.Here you are, 20,64.
Is ~1.8m average by your classification?In theory, 21 is ideal for average height, less than 21 for tall and those who wear wristbands, more than 21 is good for shorter guys.

Are you still using K7 Lime? I removed the lead at 3 and 9 o'clock and put 2 grams at 12, completely changed the racket, became more manageable and more stable. What lead configuration are you currently using in yours?If that’s a TC racquet you are referring to, then take off the palettes, check if the two upper lead slots are empty or not. If you are lucky and they are empty, you can move up there 20g(2x10g)of lead from the bottom slots. That would bring you to ~20.95 without changing static weight, but balance will shift to 33cm.
Your racquet already has pretty hefty SW and that makes it much much harder to achieve 21.
But 21 is no magic number. I like my frames to be around 21 too, but there are some other mgr/i spots that worked for me well too. 20.30 for example for TC100 with SW345.

Had the same problem with K7 red I had first batch and later batch frames, both seriously lacked plow at standard weight. Tried and failed adding weight, I just couldn’t get it to perform as well as my TC97 16x19. Still use a K7 red for feeding when coaching and for a bit of social tennis, it’s sublime around the net.
Interesting that you added weight to TC97, I play mine stock and it’s solid.
Got it. Are you playing with what currently?Hi, Paulo, I sold my Lime mainly because I am not an 18x20 guy.
