Simple frag plugs

[kuatto]

The plugs will hold about 8-12 polyps and you can drop them down into a crevise in the live rock to spread across the rock.I was reading somewhere about using very thin pieces of plexi to glue frag onto.When the time came to frag them,they peeled off real easy.Has anyone tried this,or would it be a waste of time?
I'm with Chad,I hate trying to pry zoos off a plug,just thought the flat plexi might work.
