Personally I don't like to see those kind of crimps on solid core cable.
I was taught that they are intended for multi-strand cores.
Definitely you need to check with the manufacturer's info with the red/blue/yellow crimps - some (very few) are suitable for class 1 (single solid). Some are stated as only being suitable for class 5 and 6 stranding (flexible and extra-flexible). Most of them will will be OK for stranding class 2, 5 and 6 conductors though.
