I can't answer for RocketRod, but I work for a company that manufactures harnesses and electrical products for the aftermarket. We see problems a lot when people don't provide the wire with any type of strain relief. Where the bare copper wire goes into the butt splice it gets flexed until it fatigues and fails. Heat shrinking the splice as you showed will provide the needed strain relief. We use the method you showed as well as the perma-seal splices in a production environment, and I'd be surprised if I've had more than 4 returns for this type of failure in the last 3 years. We don't soldier our splices, but we do have the proper tools which helps a lot.

As far as pull-out goes, it really pays to have quality crimpers.

Completely agree. I guess I'm spoiled and never took price into account. We buy the perma-seals in such bulk quantities I just grab them off the shelve when I need them for personal use.
