Yeah, after I saw that Oopla somehow managed Butter Ninja and Seeing Red on almost any song, I tried it myself, and it worked well, after some training. Ultimately it made the game easier for me, since before that, I was spending too much time thinking about which color to collect which resulted in many mistakes.
This strategy makes the most sense for faster songs (traffic>220), because there you only have to collect all reds and yellows (and whites obviously), and practically don't have to worry about anything else - of course for those songs Pusher is sometimes more suitable...
As for slower songs, I am still figuring out what to do, but the best strat is probably sth. like to save some high value blocks while making large green matches.
