Interestingly like golf gear, hackysacks now are rated for various attributes, stalling, bounciness, etc, and there are websites devoted to rating the many options. Back in 1983, I believe there was one sack. Is life really getting better w so many options? There’s even a preferred hacking shoe . Jeez.
I went for the Sandmaster, a top rated beginner sack. few deals, other than drug deals, are made wile hackysacking. Golf wins on that score.
