The CP has the same PW29 Zinc block as the Standard MIM Strats do.
The Highway one has a steel block, PW36, not the best but the AV style 6 mount hole bridge is much more upgradeable.
But I like the CP 60's neck more; smaller frets, tuners more to my liking. Now, the very first batch of CP 60's upon introduction had real good stuff, including US made 69 pickups, but those are long since spoken for.
I want to recommend instead the MIM Jimmie Vaughan Artist series; better guitar for less money than either.
