Well, I wouldn't really call it an exploitation, but it does make the game very easy. Even in Hardcore mode.

Just by making the shooting angle smaller, you could make the game harder ;)

I get the idea, but forst of all, this way it takes a lot of time to get to the top. Also, there will be fully filled rows where this tactic just won't cut it and some triangles could easily delfect the balls. My record is around 18 on Hc. I would love to see a vid if you can beat it with this technique. :)
