i would probably suggest against that. I'm new to fly fishing myself.
I spent $40 on flies online to bring to belize.... they were acceptable, but didn't get anywhere near the attention from bonefish that the local flyshop flies did.
I also went to army and navy, and bought 'copies' of flys that I got at michael and young for stillwater fishing. the MY flies outperformed the army navy ones by a long shot.
with a few $ more your getting better hooks and quality materials. if your going that far to fish and spending money on gas. spend a couple dollars more and go for quality flies. at least that way if you don;t get into fish you can blame yourself and not your fly.
