A headsail on a 'furler' can only be reduced by 30% SA and still
retain any good shape. Beyond 30% reduction and you wind up with a
'BAG" shape instead of a usable sail shape for any 'upwind' work.
135 X .70 = 95% So, you can reduce a 135 down to a 'working
jib' (100%) size without shape problems. A 150 can usually only be
reduced to a 105, et

That's consistent with what I've experienced. I generally end up taking a
second reef in the main before rolling any of the 150 in.

On any masthead rig, that's the way to go. The foresail is more
efficient than the main.

Additionally, when properly reefed, the main gets flatter (less heel
and weather helm) and more efficient, with less drag.
