Starting a new board.

The board I have in mind will be a copy of these.  There are somethings that I like about each of these boards.  I'll take the best features of each one.  The quad is a 7' 3" S7 Super Fish.  The tri-fin is a 7' 4" Gotcha.  My next step is to copy the outlines and design a spar.  I want to take the Gotcha out in the water in the next few days.  It's got more rocker, it's thinner and not as wide as the Super Fish.  I think that'll work better for the conditions here.
