Basically the same stiffness and syn gut, now the question is does the same stiffness transfer into the same arm friendliness?

Yes, it should.
(In my experience, low stiffness polys do feel rather soft. Although I will admit that multis tend to be more arm friendly.)

Ok, this has been on my mind for a while now. We are all here to learn and help, I hope.
The keys topics are: Subjectiveness and Vagueness ( where we are a lot here)
Now Objectiveness and Specificness ( where we should be going)
This should be a goal for all of us.
Our threads will be much more helpful, efficient and collaborative....

OK. This desire for objectivity and specificity is why I believe that these measured test-numbers are important.
These numerical results here are not vague or subjective.

True they are usrsa test results.
This is a copy of their test procedure.
Test Procedure. All strings were tensioned to 62 pounds and allowed to sit for 200 seconds. Then the string was hit five times with a force equivalent to hitting a 120 mph serve. The tension loss represents the total amount of the relaxation over both time and impact. The stiffness value is a calculation derived from the amount of force created at impact to stretch the string. Lower values represent softer strings and lower impact forces. Higher values represent stiffer strings and higher impact forces.
But this is only one piece of the puzzle. Sure I am not arguing the softness. First it is an 18-gauge string. Thinner strings will be softer. It this test number import, sure.
depends on what is important to you. Softness, like you stated above both TW's string database and usrsa (tennis mag) document their dynamic stiffness. Now if you do a comparison, you will find TW dynamic stiffness is higher. Both still in the range of 156 for usrsa and about 180 for TW. They both have different test process. So in order to be objective it is important to compile and analyze all the data.
So going back too important. Why is this “important”, you really did not state clearly why?
So let me do so more mind reading again.
If the importance is solo stiffness. Sure it is important if you are seeking an arm friendly solution for a client. But is that it, no. It should not be.
It is a start. It is a good start thou to narrow down some options for someone.
It is the first place to start (stiffness value /dynamic) for someone. Especially if you need to find them a comparable string.
But before I write a book. All I driving at there are much more factors to equate in.
The Frame, The String Pattern, Tension loss, Targeted String Tension, Player's Swing (fast, med, slow). these are a few key elements that should be factored in.
Arm Friendliness
String Breaker / Durability
String Life (goes dead ~)
So to end to the importance factor, it not the stiffness value ...the importance goes to the player.
Getting them the very best string solution that complements their frame, physical capabilities, game, level, mechanics and more (the more you know helps) ...
Example: ok this a soft string. Important yes..ok let’s string it up on my 14 year old sons frame. Hmm nope...

All of these characteristics are outside the category of strings. (BTW, the word you want is "complements.")
I'd love to see the database that measures and objectively correlates the player, frame, physical capabilities, game, level, mechanics.

Reading other threads and people's opinions, I've heard that if I string my polys at a higher tension like 60 lbs, I would lose tension much faster than stringing at like 50 lbs initially, is this true?

I cannot find a Tennis Industry magazine article String Selector more recent than 2016.
Here is an article on racquets:

Sorry.

Would be great to have an "ultimate Hybrid " thread w string choices, tension and Poly/Gut versus Gut/Poly

I have a question. I am having some problems with poly/ multi hybrid setup and When freshly strung, string bed seem to be very hot springy. and it doesn't pocket the ball well. I am thinking about pre-stretching the poly in Mains prior to stringing it, would this help cut down on springly string bed when freshly strung ?
and is there a way to pre-stretch the string on the machine ??

I found the answer on this TW videos for prestretch. but do you guys think this is a good idea for poly ?

Currently using Solinco Confidential at 55 lbs in a Prince Twistpower 97 (to be honest a very powerful racquet for a 97 head size) I tried the string out because of rave reviews from a lot of different outlets and a few hitting buddies, but I am just not liking the dwell time and “plushness” or ball pocketing of this string. I get that I am going to have a relatively dead/crisp response when using basically any poly strung up this high, but I would love a string with similar levels of control, but with just a little bit more feel. I’m not super concerned with spin generation, I generally opt for a 16/16L gauge just for tension maintenance and added control, and I also generally don’t like textured strings or shaped ones (save Head Hawk Pro and Revolve for the first 10 hrs lol) I used to use Luxilon 4G at 55 in a Prince Tour 98, and honestly kinda preferred the ball pocketing/feel and control of that, have yet to try it in this stick yet but I’ll be sure to give it a go soon. Anyways, thanks for the read! I’d greatly appreciate any suggestions

After noticing that the stringbeds of the v12 RF97 and PS97 are quite open in comparison to the Ezone 98, I wondered whether the string numbers (e.g. 16x19) and headsize were enough to evaluate the spin potential and launch angle. Hence, I have been measuring the average cell size for the central 99 cells of various rackets. I selected 99 cells since it equates to about 100cm2 or 16 sqi of the racket which is a reasonable 'sweetzone'. Below is the list so far, and what is interesting to note is that the 85sqi 18x20 MAX 200G has a more open stringbed than a 98sqi 16x19 Ezone for example. And the RF97/PS97 has very large cells although it's not known as a spin racket. Is headsize and whippiness the most important feature in 'spin potential' rather than the actual stringbed number/density?
| Name | Strings | Average Cell Size |
| RF97 Autograph v2018 | 16x19 | 1.5 |
| Six One 95S | 18x16 | 1.65 |
| Six One Team v2016 | 18x20 | 1.25 |
| Pro-Staff 97 | 16x19 | 1.5 |
| Ultra Tour 97 | 18x20 | 1.15 |
| Graphene 360 Radical Pro | 16x19 | 1.3 |
| Graphene Touch Speed Pro | 18x20 | 1.15 |
| CV 3.0 Black | 16x19 | 1.3 |
| Vsense 10 325 | 16x19 | 1.25 |
| Ezone 98 2020 | 16x19 | 1.25 |
| Max 200G Pro (1990) | 18x20 | 1.3 |
