If you use the "RG6" or a clone with the aluminum shield/foil, be sure to use crimped connectors. Aluminum really doesn't take solder well at all.
Yes. And let me add that there is nothing sacred about soldering. :-)
Think of all of the billions of crimped F connectors in all of the 75 ohm CATV systems in the many thousands of cities throughout the world. Almost none of them go bad, unless they were installed improperly.
