|Hello, Regarding copper vs stainless, it really depends on your water quality. In my area I have seen copper connectors get pinhole leaks, but it's rare and takes many years. So, if you have frequent problems with copper, switch to stainless. Stainless might not like softened water because of the higher salt content however, so I would stick with copper if you use softened water. Some benefits of stainless is it's greater flexibility and that it doesn't work harden like copper, so is easier to make work in tight places. With either type of flex connector, I like to make sure it has a true dielectric built into the ends. You can tell because you'll see a plastic ring between the nut and tubing, along with the rubber washer.
About heat traps, the shape of the trap doesn't really matter. What does matter is the depth of the trap. I like to get at least six inches of height in the "trap".
ps, with either type of connector, go back after it's been in place for six months and re-tighten the nuts. The rubber washer can shrink, making the fitting loose.
