I made this DIY swallow tail myself and it floats in powder well and carves superbly due to the camber which still has plenty of spring left in it. Just not going to get any snow time as I have too many decks and really like to ride switch.
It started life as a 161 and now measures 157, but the effective edge is unchanged 1230, some minor scuffs and ptex repair work done, but the base and top are in good condition.
If you are not fussed about riding switch and want a very cheap powder deck this could be it.
