Nice Camel! I've made a note on my instruction sheet to test fit those outer struts just in case.
Darren, there are so many rigging mediums I'm not sure where to start. You've got stainless steel wire, fishing line, monofilament thread, EZ line, stretched sprue, elastic thread, human hair (yes, modelers do use this ), etc. The list goes on and on.
I've tried most of these (at my age I'm hanging on to the hair I have left ) and the one's I use the most are the steel wire and the EZ line for most of my rigging, and the stretched sprue for shorter runs like control cables. The keys are in how you prep your model and the rigging sequence itself. I study the instructions carefully, determining where to pre-drill my attachment points and what medium I will use where. The sequence is important when attaching it, especially around long runs. Here I have found it is best to work from the inside, out, so you do not have to work around what's already installed. With the three mediums I use, my mounting holes do not have to be drilled all the way through. With others, especially monofilament thread and fishing line, many modelers will attach one point and feed it through a hole drilled completely through the wing, CA it, trim it flush, and touch up the joint with the appropriate color paint.
I hope that helps you. It's a general description, but if you have any more questions that arise , I'll do my best to answer them.
