I only use screws and washers for jobs like this. It's very secure and if (when) I decide to change things, I don't have to remove the staples - did it once, learned my lesson!!Is there a particular reason you want to be able to remove them?
We invested in a heavy-duty fence stapler to go with the compressor:

That's the big, orange one. The small red one is the narrow-crown stapler I use for lighter work.
