Sorry, after I looked at my post I realized I didn't answer the question you were asking. I don't think you should be as concerned about the stress on the trap wires themselves. If you have 445lbs on the wire in a breeze you will be loading up your shrouds and mainbeam. Make sure your shrouds and all associated connections are sound. In addition check the tension on your dolphin striker. If it is too loose you will be putting a lot of load on your mainbeam. Greg
