Wella Boost Bounds

I have been using a mousse called Wella Boost Bounds, which is a curl enhancing mousse, as I have a bit of wave in my hair and like to encourage it with scrunching but my hair is quite fine so too much product flattens it. This product was light and had a touch of hold, but alas it is now not available, and I think discontinued. Does anyone have any suggestions for a replacement?
