www.seabreeze.com.au/Members/Classifieds/ImageViewer.aspx?id=xr6-&n=-1these boards are perfect to modify( have a look at the concaved deck), they have the volume in the tail and in front strapps to sink the deck, and chopp the nose, and there's enough room in the tail for cutout's , if you can't find a caveman have a look at an old f2 spootnik 85lt or a drop's speed slalom , you can pic up old f2's for about $200 or less
pirrad the reason i suggested a caveman slalom is because it was up your way and a perfect board to scoop the front and back foot ,they have volume between the back foot and the front foot area, and im sure they have a scooped deck, you shouldn't have to change the bottom to much just rout out the foot strapps
if you wan't to cut into the rails eg wingers and make the board narrower from between the front and back strapps you will have to reroll the rails
i allso think if you modify a wave board by routeing a flat through the center of the board you will have two humps either side, if you want to modify your waveboard to a speed board take the whole bottom off and start from scratch
