G'day

I was in K-Mart today getting some hooks and noticed the feeder
floats, they looked like a good idea for gars and mullet. I've never
used them and I was wondering if anyone has any experience of them and
if they work.

Here's a really dumb question. Are they meant to sit horizontal or
vertical in the water?

The pack suggests a mix of about 70% bran and 20% pollard and 10%
sardines as the berley mix. Is there a better mix?

I've had a look at the Jarvis Walker website and done a web search but
I can't find any info on the best way to rig them. Any advice would be
appreciated.

Cheers and good fishing.
