Hello Rob and Welcome!,
We have owned 2 different W28's and have sailed them both with and without roller furling. Being old and set in my ways I sailed with hank on sails until a couple years ago when I decided to join the twentieth century. Yes, I realize its now the 21st century, but I seem to make changes slooowly... I finally switched to roller furling for the same reasons you are considering it.
Our current headsail inventory now consists of a roller reefable 130% Genoa, Staysail, 110% Staysail Genoa and Crusing Spinnaker. We installed a Schaeffer Roller Furler and had the 130% Genoa modified (luff tape and cover) to fit the furler. We are now able to roll/furl the 130% down to about a 100% and still maintain good sail shape. For light air Summer sailing (common) here in the Pacific Northwest we use the Staysail Genoa and full 130% Genoa. In the Fall and Winter months we generally have no wind or LOTS of wind so we use the standard Staysail and the 130% Genoa rolled down to 100% when there is a good breeze.
As others have said our first reef is always the mainsail, then we start rolling up some of the headsail, and if needed put a second reef in the main. In strong breezes of 25 plus knots, a completely rolled Genoa with the double reefed main and staysail balance our boat quite nicely.
How you load your boat will affect how she sails, the 28"s tend to be stern heavy, you may find that moving gear and shifting the center of balance will have a great effect on how well your boat balances under sail.
Good luck and Fair Winds!
