I'm 5'-10" & 200# and just started landboarding this summer on a 2005 MBS Comp 16 with F3 bindings and yellow eggs. It all depends on how sloppy
the board feels - if the springs are tightened all the way and you turn too easily you need eggs. Yellow eggs are soft, orange harder, and red
hardest. The harder the egg, the stiffer the trucks are. If you get eggs that are too hard you can always move the springs to the narrow slots.
I ride on grass soccer fields and have no beaches to try but I suspect that it might make a difference in how stiff you want your trucks to be. I only
use the mountain board for kiting too so I don't have to turn too much.
I also have the springs installed in the wider slots and found the yellow eggs too soft so I changed to orange eggs with the spring adjusters just
poking above the top of the board. The board is still easy to turn but I still wonder if I should change to red eggs because I get too much healside
input and start heading too high in stronger winds & gusts. It helps to loosen my bindings so that my heal does not hang too far off the edge of
the board.
I have'nt tried riding toeside yet either.....
