Distribution of weight is always an issue if there is one two or more on a boat. especially is a small boat. Weight is usually best used when distributed around the CG of the boat which is a challenge with sand bags. There are occasions when you want some of the weight favoring fore or aft but centered on the CG is what one should usually shoot for. Sometimes CG balance is hard to determine without a fore aft balance instrument of some kind. I try to keep the boat as light as possible unless fleet ruled dictate otherwise.
There is nothing wrong with having reef points in the main and/or using a foresail furler of some kind unless you are serious about speed. My preference is to use sails suitable for the anticipated wind. On a 14.2 it is not practical to have a large inventory of sails on board so do your home work and select the best sails for the wind you expect to encounter. I would think that a main with reef points and one smaller head sail would be more than enough for any occasion. I love a furling head sail but it has its drawbacks if you are looking for speed. When you design a sail you strive to make the foil as near perfect as possible. I try to have the fullest point of a sail around 40% of the way back from the luft. As you partially crank in a head sail to reduce the area exposed to the wind you start changing the sail shape and distorting it from the ideal foil shape. The more the sail is shortened the further the fullest part of the sail moves forward which has a major effect on the efficiency of the sail. You will still get power out of it but the drag factor goes through the roof. It is far better to have a smaller sail to be used on windy days id rules permit.
