That's not that fast, and also by the time you hit apogee, it has slowed down a lot. When you simulate a really really high performance rocket like Jim's staged rockets or Bare Necessities (which could definitely have benefited from spin stabilization) with half a degree of fin cant, it ends up spinning extremely quickly, and since the air thins out a lot, it no longer has any friction slowing the spin.
And the lateral mass has to be perfectly balanced or you will get a washing machine effect and the rocket will come apart.
Sounding rockets are spin balanced like a tire.
