If You are very strong and want to fight, I think you can sail very high against the wind and with a very high velocity.
itīs important with maximal good tuning with boompotition (not to high). Use a lot of downhaul for the sail and a sail with forward power. All this recommendations are to prevent the problem that the you will have the sensation that the forward foot is going out of the footstrap (to much power for the backleg). I think itīs written a lot of this discussion (hypersonic/fronfoot)
