The red, blue and yellow crimps are usually barrel type, with a thin wall solid tube inside a thicker wall split tube.I wouldn't use them due to the nature of the crimp construction. As you know, typically they are a split tube which is simply pressed into an oval shape when crimped. Usually it's quite a thin wall on the tube and I'm just not convinced they stand up well to the thermal cycling they may experience.
I've certainly tried a variety of crimps on solid cable in the past and not had much joy (various crimp manufacturers and various crimp tools), and I've pulled far too many apart with very little effort that have been installed on sites I've worked on, so I just steer clear and use things like the SpliceLine and Wagos.
