Buoyancy

So I'm hoping that someone out there in wake world can shed some light on this for me. I was looking at the billabong garage vest and wanted to know if anyone had a billabong vest and how well it floats you.

I have a couple comp vests (liquid force team and liquid force cardigan) and they both float me differently. The cardigan barley does anything for floating. Will billabong be comparable to that or?

Any input helps
