I have a BTU. It's about a little more than a Tropical Breeze. Maybe more upfront. It's weaker than cyclone. Way stronger than any true urethane.
It'll hook a lot on backend end, under the right conditions. Its skid phase is longer than a urethane, so won't roll at your feet. It has a long hook phase, and then can snap off of that, but that depends on conditions.
It is a reactive ball.
As far as balling up to a twist, I haven't thrown that, but it's a little weaker than cyclone, comparable to Motiv's Covert Tank in some ways.
If you have a 425 rev rate, then will not have any trouble getting it to move.
