I end up in the Bahamas for bones most of the time so a weedguard gets very little use. Sometimes you are throwing into grass but there's not much in the way of flotsam to worry about down there. I would say I have a few and use one or two in a week down that way.
An unweighted fly fish slowly above the weeds gets good reactions too. I've been surprised by how far a bone will rise to take a fly under the right conditions (e.g. not tailing).
