I had 7:1 purchase with end boom sheeting and ratchet block at the bridgedeck traveler and that was bearly enough at above 15 kts apparent on my 35mKII. She had a higher than normal aspect ratio mainsail owing to the slightly less than 12 foot E dimension. I think 4:1 won't be good in anything but light air and definitely not good for not so strong trimmers.
