You changed wires right? So the lengths are different? That is certainly possible. If you want the same rake, simply take the furler forestay assembly and match the adjustments to get the lengths the same... if possible.
Mast rake: The boat performs better with a lot of rake, so if you are still able to fully sheet the main, it isn't too far aft. You can adjust the rudder rake to correct for the weather helm issue.
