A possible problem with that idea is that it makes it difficult in the future for people to find info on different tricks combined within a single thread. best bet is to create a new thread for tricks that havent allready been covered (or dont relate to a trick allready covered)
Now back to the trick. Sean told me once he had a really hard time getting this trick. heres the secret

get one spinning well, turn around 180, sort hands out, start the second. so you have the diabolos spinning in opppsoite directions, they wont collide then.
