Sean, magnets won't help you much, unless you get an electra jet and need to build the wings...
Magnets are just a better replacement for pins. They allow you to hold ribs, spars, LE, TE etc in place on the plans. Ussually I can layout an entire wing panel with out glue, make any adjustments as needed, then go to town with the CA. The average wing panel takes about 30 minutes to set up properly, and 3 minutes to glue. Life is SO much simpler with magnets. As an added bonus you don't get a sore thumb
On another note, boy I wish you lived closer. I'd love to get in your shop and hang out for awhile......
Take care.
