If you're importing 60i video, set PD's "TV Format" setting in preferences to NTSC 60 FPS. The video will get de-interlaced to full 60 FPS by PD (who knows what method). You can confirm that you're working with 60 distinct frames per second by stepping through a few frames of the video.
Then, whatever slow motion effects you apply get applied to 60 FPS video, so you have twice as many frames to deal with than if you had imported the 60i video as a 30 FPS project. This will give you true 60i to 60p de-interlacing and smoother slo-mo without resorting to other software.
