I created the birdcage and the flowers in my PI. I loved how intricate and clean a cut I was able to get with my PI. The birdcage came out better than I expected. Visit my blog, MyPaperCrafting.com for more details. http://www.mypapercrafting.com/p/melins-two-page-layouts.html
Just keep playing with your settings. Eventually you will hit on the right "recipe" for getting those cuts.
