For insulated red, blue, yellowstThe firm gave me a set of Roebuck ones = every time you crimp anything one of the handles slide off! Instead I use a £20 ratchet set bought from the boot fair about 15 years ago, Laser brand maybe? Cheap as chips but they do a good crimp and I've never had an issue tbh. Still nice and tight etc.
For bootlace ferrules I swear by my Pressmaster one though!
