It doesn't matter too much which you you choose – Guillotine variations, Darce, anaconda, kata gatame or another – they all work well. The dual from both directions greatly amplifies the effectiveness of the since as an opponent defends from one he inevitably exposes himself to the other. Make sure you have strong strangles from both front and back, at least one of each that you have total confidence in – you'll soon become a real force on the mat!
