Should, Would, Could vs. Will

[ericuva]

Can anyone provide succinct rules on when to choose Should, Would, and Could vs Will. From what I've been able to glean from grammar texts, the difference lies in the fact that should, would, and could are used in hypothetical cases, whereas will is used in declaritive sentences. A better explanation may help solidify my understanding. thanks
