Depends on side. Chingotto has matches where he may smash 2-3 times max.
If you have a really good vibora it can function as well as smash. Super easily lobs you can drill down low with virtually no rebound. Even if you miss it a bit, it’s still not the easiest to return. Less likelihood of hitting glass or net too.
While on the smash, even decent ones can be returned right at the net and when they are returned they are typically tap outs or shots that are very hard to adjust to because they are hitting right at the net with momentum and the ball above the net.
But yes, a left side player needs a good smash if playing with a righty on the right.
