There's only two reason to tie your own flies. Because you are using (read: losing) enough to make it less expensive than buying lures ... or because you like tying flies.
If you are tying to reduce the cost of your fishing addiction, then tie and fish what you want. If you want to try hair poppers, buy a couple from somebody and try them before buying all the materials.
If you are tying because you like to tie, then who cares which catches more? It's fun material to work with when you get the hang of it, and I am only just starting to get the hang of it. Tie a few up and see how creative you can get.
