I understand the convenience and purpose of a frag plug, but they are ugly as sin. Why don't more people use rubble and rock for frags? If you are a store churning out tons of frags on the regular I get it, but even if the plug is needed as support in egg crate for frags that would easily topple over... a simple solution is to take all those spare frag plug stems people cut off.. and glue those to rock rubble and use that as a frag plug! Then when someone like me buys that awesome looking frag.. I can just break the plug stem off the rock and have a nice natural rock/frag to glue into place!
