I think I've more or less sorted out the bounces at this stage - still looks perhaps a bit too wide to me? I'm not sure. Might mess with bringing it all a little closer together. I think the spin and fall is definitely too slow, though! I compared it to V13 and the shuttlecock spins much, much more quickly.
I guess I'll start messing with the change in direction at this stage before I get into playing with the timings. Don't want to get the timings looking nice and then mess it all up by adding different keyframes...!
