No doubt, separate taper crimp is the way to go. I have a Hornady TC die because it works well with my LNL AP. But my main dies are Redding. Seems to have proven a good combination.
Yes , most die makers offer a seperate crimp die relatively cheap. But ya may just keep yer eyes peeled for a single seater die in gun show/shop bargain box. Pull the seater assembly , and ya have a seperate taper crimp die.
