Clash Discs Vanilla but with more finish

I'm a RHBH with about 415 distance. I love the glide and turn of the vanilla, but sometimes find that it won't fight out unless put on a considerable amount of hyzer. I bought a Kastaplast Alva to be a more overstable compliment, but I can't seem to get it to turn enough.

With that said what would you recommend for that same glidey turning flight, but with more finish in the final 25% of the flight?
