I would have thought this would be too heavy for me too, until last last week.
It should not be possible... but I just played the best match of singles of my life

Certainly given me ideas for my Blade Team (or 1st gen Bab PS 16x19).
I know Shroud is interested.
Is the pic of the red racket with the black tape all over the racket, the racket you are talking about that is nirvana? It looks like a clash.
That is pretty!!!!I slapped on a lot of extra gorilla for this one.
Looks like some sort of PWS in the sides.
Wondering how aerodynamic it is with those layered tapes on the sides. Can you describe the sound it makes when you swing? Is it like swoosh?

Most people are not knowledgeable about boundary layer in fluid mechanics.
In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a bounding surface formed by the fluid flowing along the surface. The fluid's interaction with the wall induces a no-slip boundary condition (zero velocity at the wall). The flow velocity then monotonically increases above the surface until it returns to the bulk flow velocity. The thin layer consisting of fluid whose velocity has not yet returned to the bulk flow velocity is called the velocity boundary layer.

It is in the usual SW2 range.

MgR/I is a weird metric, makes no sense. There's no intuition behind it, not sure where it originated.
More physics-based discussion on MgR/I
I'm creating this thread after deep-diving into MgR/I. I found it particularly intriguing since the spec has been heavily discussed on this forum, with some using it as a focal point for racquet customization, but I found it initially difficult to decipher what exactly this spec conveys in terms...

Just make sure it is 21 for your setup

I find it makes alot of sense in that you tune the racquet for contact. Is the racquet lagging or speeding up or neither at contact? Thats what it speaks too. That said i dont buy that there is some magic number since everyones arms are different

TDLR after thoroughly breaking down the formula, my conclusion with regard to angular acceleration is that MgR matters and moment of inertia (I) matters. But they should be treated as separate factors. I fail to see the logic in combining them as a ratio.
Then why don't you linearly combine them like a*MgR + b*I, with a+b = 1 and suggest the best values for a (b = 1 - a).I created the thread you linked

Nope, units are different. One is for torque, the other for moment of inertia. Makes no sense to combine.
The road is long
With many a winding turn
That leads us to who knows where, who knows where
I was thinking about that. If the units are different, is it OK to take the ratio and how can it come out to be a number like 21 without units?

i want this the Magic Ugly Racket! it is so ugly it must be good or why sane person use it?!
i have the ugly angry lady at tennis who beat me lots, but when i beat her with ugly racket she will be upset and i will be happy.
where i buy this?

I don’t believe that. When you search MgR/I on Google, the top result is almost always from this site called impacting tennis. That site is intellectual BS, sorry. Lots of conjectures, nothing to back it up.

Looking back at very old threads, some argue that MgR/I yields angular acceleration. Yes, the units are those of angular acceleration, but you have to ask yourself in what scenario? When you fix the butt cap to a point and allow it to rotate like a pendulum from a horizontal position, the initial angular acceleration as the racquet swings downwards is MgR/I. But that acceleration is purely driven by gravitational force and wouldn’t be relevant to most of a tennis stroke. The only segment of the kinetic chain where it would be applicable is in the racquet drop, before accelerating upwards and horizontally.

800g is not heavy for @Shroud
Shroud
Talk Tennis Guru
Hmm. It sounds like a challenge. Half way there. Though its unlikely I could realistically add 400g MORE to a racquet. Thats like 800” of lead.
4 strips of lead like I add now is pushing it. Trav wraps between the grommets so he can add enough weight. Lead stays on for me mostly but he says no. Probably the paint. Some sticks don’t do well with lead.
Ok. Thinking about it, i would warm up with a 2 lb hammer when I played leagues. I would shadow swing all the shots except for bh overhead. Anyhow in that light yeah I could do it so could you. Especially if using the kinetic chain.
Ime the issue with such weight is deceleration on the serve.

People tend to overestimate the importance of stroke technique and underestimate the advantage of playing with a sledge hammer.

G.O.A.T.
Turbulent air flow vs laminar air flow is going to be based on how fast the tip if the frame is moving and its duration. Air may or may not be moving turbulently as the swing occurs, but it probably does not matter. The duration of the swing is too short and there’s too much mass in the magic racquet. It matters to an airplane cuz lift is provided by differential air pressure due to air flowing faster over the top of the wing surface.
travlerajm
Talk Tennis Guru
Did you do you do you Re calc to verify that?
I play with a constant 20 mm beam frame which optimizes my aerodynamics.Too many assumptions. My guess is turbulent, but you don't feel any air resistance cuz the swing duration is over in less than 0.2 seconds.
I also don't let my hair grow too long as it might impede my fast movement to the net for volleys.
I would suggest using CFD (Computational Fluid Dynamics) to verify that @jayvee
Nothing is too heavy for @Shroud
If I was an airport security officer, I would be scared to see this in the luggage and detain @travlerajm for questioning.
NJ, I had a racquet I gave to a homeless guy that lived in a pickup truck by a local park. He practiced several hours a day and was convinced he would win the US Open in a year or two. He had been a really good D1 scholarship baseball player a few years before and could really hit the snot out of a tennis ball.
Next time I saw him, he had cut up a bicycle inner tube and wrapped it around the racquet head. It looked remarkably similar to travler’s frame. It hit like a cement block.

I filmed some vid of me hitting with this monstrosity today. Will post it soon. It seems like it naturally helps my forehand feel more grooved, like it’s on training wheels.

Gorilla Tape - the incredibly useful customization tool
I have found myself using this more and more. I still use lead tape for when need to add a ton of weight in high density under the grip or inside the hoop. But I love Gorilla Tape for: 1. Securing multiple layer lead tape on the hoop by adding crosswise 1/4” wide rings of Gorilla Tape around...

The astute observer will note that it’s actually the same racquet that I used in my most recent MEP battle (the one where I’m wearing dual knee braces, dual ankle braces, back brace, and backward cap, and ran out steam in at the 75 minute mark, and went down in flames in the super). But the racquet was missing the extra layers of gorilla. Might have made a difference.

Many post 65 have 75% dink and mooning games, take that away.... pickleball time.
“returned” to heavier static weight and leather grip/OG setup after quite a few years today. Enjoyed it very much the heavier setup. It is only at around mid 340g though. lol
Almost 4 hours straight over 5 (competitive) sets, and I think I have missed the heavier setup and I thought I didn’t pretty well considering the (new) setup. Will stick with it and see how it fares for the next few weeks.
