Sorry to say this, but the 'I am not as accurate as I like to be with my side/back kick' made me wonder.
We have pretty specific specs we have to follow for our breaks, so many hand or foot techniques, spinning, jumping, either leg, both legs...
Anyhow, if you are good in the spins, more power to you (I am not and it took me a total of 6 tries to do my spin-side and actually breaking last time I tested) but there is so much more in the arsenal than just spins. I personally like frint kicks (keep your toes back) my son loved Axe kicks and as more advanced BB run jumps, jumps and spin jumps are making things more interesting. We generally only break once in a 2 month cycle. But it is only supposed to be a check for the accuracy of the technique anyhow...
