The chariteristic that sets both the lynn and the lando apart is from the other lib and gnu boards is that they have a longer than normal side cut, 8.75m in longer versions, where most boards are close to 8. this works well with a high speed aggressive riding style hitting natural features. It also seems to help in steep sketchy sections as it grips great even though it has mellow mag.
the lando has the org throttles from the darkseries, a little torsionaly stiffer than the lynn and more setback. I would call both the lando and lynn, directional twins, with all mountain freestyle in mind. The billy goat has a little less sidecut, and is built as a directional freeride board, with the shape, sidecut, core all directional. Its also damper than other lib/gnu's. I've never rode a billy goat, but if you search snowolf has a review of one.
