Because 07A still has some topsheet softness left and I prefer it to have better control than Hyper. I may have spinnier pushes and loops with Hyper but I have better ball control with O7A.
Some exercises:
1. Fh to fh diagonal
2. Fh to fh down the line
3. Bh to bh diagonal
4. Bh to bh down the line
5. Fh and bh while other is blocming only but this is more advanced.
Hyper is very hard and feels like a 41 degree Hurricane 3 in the backhand. It is a high performance rubber that needs high level of skills. I am settled with the O7A as a bh rubber
1. Placing the ball on the same spot develops control and consistency of placement and it is being taught as part of the basic strokes.
2. A stroke like block and some other strokes have both active abd passive versions depending on the skill of rhe players and also the intended drills.
3. Yes...
They feel just different because the Yasaka EO is walnut outer but i would I choose it over the All Around Carbon because it is a proven good cpen blade.
