Dont Do the Far bomb method! Its slightly harder. Use the medium bomb.
uf+2, 2,1~net, uf+2, 2,1~EXbomb, midbomb, 1,2,3~close bomb, net, u+2, b+2, 1,2,1~ragdoll+throw.... 75%
To make the 1,2,3 work off the medium bomb, just do a slight dash in as your doing the medium bomb. Also make sure you hit the 1,2,3 kind of low.
This method is much easier then the far bomb method.
If your not sure about what i mean when doing a slight dash in as you do medium bomb, then you can look at this..
at 51 seconds the combo starts and at 56 is where i do the small dash foward..
