In this video Stephen Kesting (www.grapplearts.com) does a great job explaining both gi and no gi methods so you don’t have to pull guard. We at Synergy Martial Arts discourage our students from pulling guard, we want our students to end up in top positions because of our emphasis on self-defense matieral.
I know many people feel that guard is a superior positon for the person that pulls guard, but that statement is usually made by someone who grapples with opponenets who are in the same weight class and on mats. I know from personal experience that pulling guard on concrete is not the best idea for your skin.
While I was training in California with Paul Vunak he had me grapple from our knees in his driveway against a guy who was much larger than me. Due to our size difference I did pull guard and used a scissor sweep gain knee mount. When were done I saw the results of the guard pull, my knees were scraped up and my partners elbows were scraped all from about 60 seconds of controled grappling.
While some of the scissors sweeps in here may result in the same if you used them on the street they do not allow for your opponent to use his weight to press on you like in a traditional guard pull.
