What are the main disadvantages of using thicker string? Less feel? Less spin, smaller sweet zone?
All things equal so if it is the same string just thicker, it will feel less lively. The gauge of the string should be a decision based on the spacing of the string bed and each players comfort with it. So if an open pattern and you want to have more control then go thicker is one way. In a closed pattern, you may want the opposite and open spaces between strings so you go thinner. It should also affect launch angle a bit with thicker having a bit less.

TC95s are on my desk. :) I thought head size will be smaller. Seems more like 97-98in. That's good news for me, I need forgiveness.

Another question, if I'm stringing my TC100 in range of 22-23 kg, what tension shall I used for TC95? 20-21 kg?

I had a practice today playing TC100 strung with firewire at 22/21kg. It was nice. Hope it lasts good time.

start with rslyon or silverstring if you have a pack of it. around 46lbs (20.8kg)

So, here is how K7 Lime stands strung with 17G Kirshbaum Pro Line II and Solinco Hyper-G hybrid @21/20kg.
Weight 347g
(Strings +16g, Angell Hybrid Grip +9g, Overgrip +5g, dampener +2g)
Balance 313mm
SW 321
Flex 64RA
RDC String-bed stiffness 59
ERT-300 dynamic tension 36
Recoil weight 166
Mgr/I 21.15

String spacing looks the same as on 18m both TC97 and TC95. And why would it be different when they all share the same grommets. However the hoop of K7 Lime is ~2mm wider and ~2mm shorter than TC95’s and TC97’s. Could be just because it’s freshly strung!? Tension is the same, but different strings. Will check later again when strings settle in.
#3 grip runs bigger than on custom line.

Hopefully I’ll get some court time to hit with it tomorrow. After that I plan to add some weight at 3 and 9.

2 grams of lead at 12 o'clock would add how much of swingweight in K7 Lime?

Thank you all for tension suggestions. I have a tournament tomorrow, shall I try TC95? :D I remember first time I tried TC100 we won local doubles tournament.

Basically it was extremely good year (even more than year) with TC100s. I won a lot, came back to the more serious racket weights and found out that I'm still capable play in heavier racket category (big kudos to Saleem). It is very interesting what TC95s will bring here. :)

Am I missing something - the head sizes looks almost identical :unsure:
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.

Does ASL3 and TC100 have the same head shape/size? Or one is a bit wider and other one is bit longer on bottom?

Btw, any advantage/disadvantage of lower swingweight? Does it affect a heavy ball on higher SW? Let's say both racket is the same except the SW, thanks

Did my homework this morning:
https://www.dropbox.com/s/fryh6w3klvoioez/IMG_1527.jpeg?dl=0

Some data:

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. :)

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. :)
How do you even calculate this? Is there calculator anwhere or at least a formula?

Guys, 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.

I really like the feel of the K7 Lime. However, I am still more comfortable with my TC95s. They are, of course, both exceptional frames. Makes quite a lot of the stuff today 2nd rate, IMHO.

worst case scenario, play with what feels good. dont look at the 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.

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.

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.

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
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.

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?

The video is by Paul Angell who as you may know is an engineer and racquet designer so it is not my video.

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.

You can also use the customization to to increase your SW by 3 point and see what you get.

Ask Paul who is correct here @Racketdesign. If that increase of 6 points is accurate you proven work that Newton did 300 years ago wrong.
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. You can debate Newtonian mathematics with Paul :-D

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. I’m not going to believe what I seen in that video is accurate.

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.

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?
