From what you're describing it's a good set up either way. At this point do what's most convenient for you to place and remove. As for frames, you want old dark ones. They have the most smell when things warm up.
Swarm traps are like placing bait when fishing. Sometimes no matter what you do you get nothing, other times it's the exact opposite. The more traps you place the better your overall odds but I find I get about a 10% success rate. As the season goes on I end up pulling my traps one by one on the way to swarm calls. They're fun to place and watch, and I still do. However, I get much better results from swarm calls.
