Eggulator has a forgiving and balanced rocker with soft rails and a slight single concave to double between the fins that flows into a scooped vee out the tail that allows easy rail to rail turning with great drive! Works with any fin setup, thruster, 2+1, or a single fin. The HP version has a slightly more pulled in outline, more aggressive rocker, and more tapered and sensitive rails. Both work great as a squash or a rounded pintail.
