No I haven't tried the Emerald Pool/Broderick/Grizzly route. It looks like quite a ways to climb through off-trail. Looking closer, it doubles the off-trail elevation and distance. If I had lots of free weekends, I'd probably try it out. But I am having trouble trying to find any time to get away.
If you are heading up for sunset pictures, the Broderick/Liberty route can add some variation. I went up once with MooseTracks Laura, and came down that route last summer with my 10-y-o daughter. It was more difficult descending, tougher on a kid than I first thought it would be. Going up is better. But...if you are going to be descending after dusk, you should go around Liberty, so you know the route better to return in the dark.
If you're ok on the E-ledges, I think you would like the climbers route.
