Learning new strategies

I joined a coaching site called cardrunners.com a week ago. The guys whom run it are huge online winners and very young to boot. Their strategy is to play an aggressive game in position and pretty tight OOP. This is a theory that has eluded me up until now and I like it. It just makes since. I'm going to focus all of my time on $5 S&G's for now and then work my roll up to where I am playing some of the high BI S&G's. I probably won't play too many MTT's for while until I build my BR up a bit. I tried playing a very LAG strat for cash games but I don't like it. I really like playing tourneys more so I think for better piece of mind I'll stick to that. Cash games are extremely difficult for me right now.
