Are Carvin Strings Tapered?

[DavePlaysBass]

I searched but did not find what I was looking for.

Do they taper more than just the B string in these? I am looking at trying the 45-65-85-105-128 Nickels. I gather these are a variant of Labella Slappers.

I have two sets of the Carvin 5 string sets right here (one regular and one light set), and the B is the only tapered string. I assume they are the same as the four string sets, minus the B.
