They are more surf boats, or just rippin boats than flatwater freestyle boats. The only thing they won't do is flatwater backflips. They are perfect in waves, especially choppy ones. Light and easy to fling around, but do not ride nose high. You can ride them REALLY fast and they handle fantastic.
My Trinity EVO -2 and Madmat's Envy -2 hulls ride identical. -2 is is the perfect length. I can tell you that the Kawi Trinity one will add a TON of low end to your boat due to the loss of weight. Mine is 103 lbs. I have had ZERO issues with the hull, Foam is still dry, no cracks, no problems with engine mounts, nothing. It is unbreakable.
I think the Trinity is built a little better...(still dry foam after five years)
