My 6'0" Austin Twinzer mini-Sim (in avatar) is my go-to board for everything but hurricane surf. If you want to see it or send pics of specific parts, let me know.
I've ridden mini-Sims from Hydrodynamica (Joe B.) and Vernor. Joe started off the movement and Vernor makes a quality product, but I think Austin really captured the "planing hull" concept the best out of the three. Just my opinion.
