Pros : I have used this type of wire for many years. To me, this gauge is a must. I use this gauge for hooks primarily, but it can also be used to reinforce joints on foil or corners on 1/4" and up came. A must for every copperfoil crafter.
Cons : None
Other Thoughts : I have also used this gauge to use as "came" on free-form panels, and it does a great job. Be sure to stretch the wire first if using that way.
This wire takes solder fairly well, but since it transfers heat to other metal areas --- came, etc it works best with lots of flux (a lot). When using flux this liberally, you need to be extra careful to keep surrounding areas clear of flux or you will get solder where you don't want it.
