It is hard spotting flags when going down wind.
Everyone is in the same boat at the top mark ** so spotting flags or not is fair.
I prefer that to the rib at the windward mark raising a "this is the last time you pass this mark" shorten course flag. As it is a pain when they are fishing people out so you miss the flag.
Personally I like any course that I sail without having to count which lap I am on, so I'd support either this or the "go through a gate upwind" course.
The lack of gate in the one Will drew might allow a symetric boat to give us all a scare and Slippery WW a chance to show us how effective soaking low with the assymetic can be (as shown Weston whilst the rest of us were using our kites as fishing nets after wiping out in flying gybes). Maximum respect for the handling skills either of these options require.
