I'll chime in. I ordered all new sails for my C34 and decided to go with 135 for the Genoa, I don't see the point in reefing a 155 (down to let's say a 135) for higher winds, in lighter winds where the 155 might be a good fit I use a gennaker which works better anyway. My north sails Helix points almost as high as a Genoa anyway, being on a furler it's just as easy to use as a Genoa as well.
