I think you'll end up liking the Shryke a lot. I find them to be longer than the Tern, and just a tick more stable. The Shryke is less likely to go bombing right and not come back. I don't bag the Ballista or Trespass, but I really like both molds. Just perfect, effortless distance without being too flippy.
I had a Tern in the bag for a while, but when the Shryke came out I switched it up. The Shryke (for me) was simply a better disc. It didn't flip over as often and provided better speed, distance, and glide.
I would get a star and champion Shryke in the high 160s or low 170s and see what you think. Its my go-to disc for open distance bombs.
