Hey Joe, IMHO, Four to one may be underpowered for heavier wind, unless you take it to a winch. Not sure if your traveller is mid boom or end of boom.
The system on our 34R is end of boom and we have 5 to 1 course and 20 to 1 fine and the higher ratio is needed when she's powered up which is anything over 8 knots going upwind when the apparent wind hits 14 plus. Saw something online that showed some boats like J-105s rig their mainsheet five or six to one for high wind days and unreeve a block and convert it to four to one for light wind races. You may want that mainsheet at Bacon's.
