The key word in your question is "regularly"

I've caught 'em on flies, but can't say I can do it regularly.
The problem I often run into is BG...they are much more aggressive to flies than Tilapia. In the presence of BG, about the only way I can catch Tilapia is to sight fish, bonefish style, and put the fly right in front of the Tilapia....that usually works.
