My previous headsails included a too-big #1 and a too-small #2 and lots of sagging and poor performance in a freesh breeze and when half furled.
SO for my new headsail I went for half between in terms of area and with a reasonably high-cut foot, going towards a yankee, but not quite. Benefits of this (for cruising) are higher foot = better visibility under sail. But more importantly it's a better reaching sail (leech less likely to curl in and stall) and also when I start to furl it the higher sheet angle gives me more tolerance as I start to move the cars forward i.e. I can furl it furthe
