Flexydually - Cheetah w/eSun PVA for support

My Flexydually arrives today for my Taz 6. 90% of my prints are done with Semiflex and now Cheetah. Problem is the support material is such a bugger to remove. So I was hoping to use eSun PVA for support so I can dissolve it out of the very tight spaces in which I must use support.

Does anyone have any experience/advice for this?
