I agree with Barry on this one.
I also think that it shows little knowledge of tactical racing to put a Wing mark, gybe mark, B mark on the first lap of a race course. we all know that the pecking order is established primarily on the first leg, putting a reach mark immediately after the First weather mark just solidifies this order.
Put the reach leg on the second lap.
Another problem w/B marks is that often RC's set them at the incorrect angle giving you 2 legs in which to parade around on. Make sure that at least one of your reaches is high enough to be fast & hairy.
