Yeah, I hear you Bob. I used to solder all my joints as well until I read an
article that tested crimped versus soldered joints for current carrying
ability and physical strength at high temperature (high current loads). The
crimped joints won out, but not by a huge margin. I've switched to crimped
and find they are a bit less trouble to make but take more care than
soldering to get it right. With solder you probably have a better chance of
getting a good joint - with crimping you can get a better joint if you do it
right and a poorer joint if you do it wrong.

  From what I learned today, Fred, my new crimping technique involves
stripping the two wire ends, slipping a piece of shrink-wrap over one and
moving it back out of the way, twisting the wires together and then applying
a nice hot soldering iron and some rosin core solder.  I listened to those
outspoken proponents of crimped connections and allowed myself to become
convinced that the technique works well.  Maybe it does for you but I'm
POSITIVE that my soldered joints are secure.  I'm positive that crimps may
be secure.

size.
    The result usually isn't pretty but the terminal has definitely flowed
    around the wire! I use heat shrink for insulating the joint.
