Received the custom SS teflon lines from TS Flightlines. Very well made and not that expensive. The angles of the lines are perfect and allow them to use the adel clamps that also secure the CHT probes.
Worth the additional investment vs. the copper lines and are much more robust. Read a bunch of builder articles on VAF and there were mixed experiences of not flairing the copper properly and some not being properly secured. I'm sure if done correctly, the copper lines are fine but I decided not to use them and do an upgrade.
