The above comments are correct and present the strongest profile to the loads being applied by the spinnaker but are not necessarily the fastest. This has been hinted at by comments related to mast breakage with the N17 and even Macca made a comment that you trim the mast rotation to the mainsail trim. So... how bad do you want to win and are you willing to replace your mast and mainsail?
