Soft Body Acrylics

The other day I was picking up art supplies and was drawn by this vibrant colour which I  couldn't resist.  Normally I use heavy body acrylics but so far I'm really enjoying this consistency...for now.  I wish Liquitex carried a range of vibrant fluid acrylics, like Golden, but I definitely still prefer the heavy body acrylics.  And I still want to try the inks and do love the spray paints and paint markers, too.  They're great for layering pattern and colour.  Has anyone tried the inks?  I'd love to hear your experience with them if you have.
