After YY released the VT series racket, the collapse problem was basically controlled within the acceptable range. The next Duora series still made people a little uneasy.

There are three recommended prevention positions:
1. Knotted holes on the head;
2. The position of the single lane of the racket head;
3. The position of the 5-12 line holes in the lower half of the frame.
==================
First, first solve the problem of the collapse of the knot hole position.
plan 1:The use of ten nails on the head is suitable for racquets that do not collapse significantly and require high pounds.

Scenario 2:The use of special rubber particles for knotting holes, black L rubber particles, is suitable for racquets that are not obviously collapsed and do not need to be loaded with high pounds.

Option 3: Use Yonex W1=2 anti-collapsing nails, suitable for racquets that have collapsed and are often used for high-pound rackets.

But if it collapses badly, there is nothing to do. Later, after the thread is threaded, it is okay, because the groove is still deep and it will not float too much.
So this racket finally chose option 3.
====================
The remaining single-line hole position, how to prevent collapse, I did not expect at the beginning that the split line and nails on the second brother-in-law of yonex vtzf2 can be used for DIY, and I would like to thank the little brother Yang Lun for providing the solution.

==================
For the bottom half of the remaining frame, the old-fashioned positions of the two-link nail and six-link nail, the universal bow ten plan, six-link nail L1=2=4 two-link nail W1=2.

Severe update plan for head collapse:
![](https://img.alicdn.com/imgextra/i1/11293736/O1CN01Z3la1g1dT8IkbE0Wv_!!11293736.jpg)
To put it simply: outer top and inner guide. Use your fingers to hold the nails on the outside, and use the tapered tip to guide the rubber body that is disoriented inside the frame so that it can pass through the inner thread hole.
=========
======================================
The last question is, will it add a lot of weight if so many nails and special rubber particles are installed?
The removed rubber pellets weigh 1 gram in total.

=======================
The second brother-in-law splits the line with nails, weighing about 1 gram.
![](https://img.alicdn.com/imgextra/i3/11293736/O1CN012PMVhO1dT8BeMybh0_!!11293736.jpg)
=================
Six consecutive nails and two consecutive nails weigh about 1 gram.
![](https://img.alicdn.com/imgextra/i4/11293736/O1CN01Ocr8JD1dT8BeaQY7y_!!11293736.jpg)
==================
The hard black T on the racket head weighs 0.2 grams.
![](https://img.alicdn.com/imgextra/i2/11293736/O1CN01vbKUQB1dT8BXEL6lG_!!11293736.jpg)
===================================
The answer is a weight gain of 1.2 grams, which is almost negligible for ordinary people who do not have a professional feel and pursuit.
The difference is actually mostly psychological hints. If 1 gram can make the racket feel completely different, it is actually good for the racket owner. The racket is not smooth, and you can change the feel by applying a bit of correction fluid. Good to serve.
==================================================
There is a question: you guys who said that the hand feel has changed significantly after installing the nails, you usuallyPlay without a racket in the sweet zoneIs it? Regardless of whether it is two or six consecutive nails, the passing string is not a sweet spot string. The second consecutive nail can barely be called the sweet zone, and the position of the six consecutive nails is obviously lower. The conversion rate of hitting in these positions is inherently low, and even the nails are similar.
