What gauge solder are you guys finding works the best?
1/8 inch or 1/16 ?
Does it make much difference?
Are you planning on coiling it around couplers or using it as standard soldering, such as feeding the solder to the heat? I've never tried the thin solder in a coil, but I imagine it would work very similar to the thick solder, possibly even better because more surface area to heat. However, it may be a little harder to control if feeding it to heat, because it would be consumed to fast you'd really have to move. So, basically, I use the thicker solder because that's what I bought, and it's what most everyone else uses.
